NOVELTY - The protection sheet (10) has a main portion which is sequentially provided with a first weather-resistant film (1), primary adhesive layer (21), second weather-resistant film (3), secondary adhesive layer (22) and third weather-resistant film (4) having a thickness of about 60 micrometers. The widths of the weather resistant films are set such that the width of the first weather resistant film is greater than the widths of the second weather-resistant film and third weather-resistant film. The sealing material layer is formed on the side of third weather-resistant film.    USE - Protection sheet wound by roll-shaped article, used in solar cell module (all claimed) installed in roof or rooftop and outdoor. Can also be used in LCD element, electromagnetic wave shield, touch panel, organic device, electroluminescent element, color filter, and vacuum heat insulating material.    ADVANTAGE - Since the width of the third weather resistant film is larger than the width of first weather resistant film, the curling of the protective sheet, laminated article and the solar cell module can be prevented effectively. The external appearance of the protective sheet can be enhanced. The delamination of the laminated portion of a protective sheet can be prevented effectively. The blocking prevention property and handling property of the protection sheet can be improved. The weight of the protection sheet can be reduced. The workability, transportability and productivity of the protection sheet can be improved. The contraction stress of the weather-resistant film can be reduced. The efficiency of the solar cell module can be improved.    DETAILED DESCRIPTION - The protection sheet has an inorganic layer which is formed in the surface of base layer provided in the second film. The ratio of the width of the second and third weather-resistant films is set within the range of 0.65-1.0. The ratio of the width of the third and first films is set within the range of 0.70-1.0. The width difference between the third and second films is set as 32mm. The difference between the widths of the third and first films is set as 80mm. The thick moisture proof film is stacked on the inorganic layer side of the first weather-resistant film. The tensile elasticity modulus of the third film is set as 2.0 Gpa. The water vapor permeation rate of the moisture proof film is set as specific value. The thermal contraction rate of the first film is set as 0.5%. INDEPENDENT CLAIMS are included for the following:    (1) the roll-shaped article has a main portion for winding up the sealing material integrated protection sheet. The cover sheet is provided in the main portion. The bending length of the cover sheet is determined by collecting the samples having a width of 20mm and length of about 120mm, placing the weight on the portion of the base of sample and by measuring the length of base. The load resistant dent of the cover sheet is determined by collecting the samples having a length of about 100mm, installing the collected sample on the glass plate and by mounting the steel ball on the center portion of sample; and    (2) the method for manufacturing protection sheet, involves producing a laminated portion having adhesive bond layers on the respective sides of second weather resistant film. The weather resistant film having larger width than the laminated portion, is bonded with the first adhesive bond layer. The edges of the first film are protruded along specific direction. The third weather resistant film having narrower width than the laminated portion is bonded with the second adhesive bond layer. The release sheets are provided on the adhesive bond layer. The release sheets are peeled. The adhesive is coated on the bond layers and the coated layers are dried, so as to produce release sheets. The release sheets are peeled from the adhesive layers. The adhesive layers formed in the laminated portion are connected together.    DESCRIPTION OF DRAWING(S) - The drawing shows the sectional views of protection sheet.
