NOVELTY - A back surface protective film (1) comprises laminated body which consists of infrared-permeability colored resin layer (11) that contains aromatic-vinyl-type resin and white colored coloring agent and has thickness of 10-300 mu m, white-colored resin layer (12) that contains aromatic-vinyl-type resin and white-colored coloring agent and has thickness of 10-300 mu m, metal layer (13) and weather-resistance improvement layer (14) that contains fluorine resin and has thickness of 10-300 mu m.    USE - Back surface protective film for solar cell module (claimed) used for solar cells in house and building.    ADVANTAGE - Low thermal storage property, heat resistance, flexibility, adhesiveness with material containing ethylene-vinyl acetate copolymer, durability with respect to cooling-heat cycle, moisture permeability-proof, and weather resistance are excellent.    DETAILED DESCRIPTION - A back surface protective film (1) comprises laminated body which consists of infrared-permeability colored resin layer (11) that contains aromatic-vinyl-type resin and white colored coloring agent and has thickness of 10-300 mu m, white-colored resin layer (12) that contains aromatic-vinyl-type resin and white-colored coloring agent and has thickness of 10-300 mu m, metal layer (13) and weather-resistance improvement layer (14) that contains fluorine resin and has thickness of 10-300 mu m. Absorption factor with respect to light is greater than or equal to 60% when infrared permeability colored resin layer and weather resistance improvement layer are outermost layer and light with wavelength of 400-700 nm is emitted to surface of infrared permeability colored resin layer. An INDEPENDENT CLAIM is included for a solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic sectional view of the back surface protective film.
