NOVELTY - A surface protection sheet and sealing material laminate comprises sealing material, surface protection sheet, and crystal nucleating agent. The sealing material has resin layer (a) containing silane modification ethylene-type resin (A), and resin layer (b) containing ethylene-type resin (B) having crystal melting peak temperature of 100-145 degrees C and crystal melting heat quantity of 120-190 J/g when heated at a rate of 10 degrees C/minute measured by differential scanning calorimetry. The water-vapor-permeation rate of sealing material at 40 degrees C and 90 %RH is less than 3 g/m2.day.    USE - Surface protection sheet and sealing material laminate is used for solar cell module (claimed). Uses include but are not limited to mobile device, liquid crystal display element, electromagnetic wave shield, touch panel, organic device and color filter.    ADVANTAGE - The surface protection sheet and sealing material laminate has high moisture-proof performance, excellent dampproofness and long-term weather resistance, improved protection performance with suppressed moisture-content penetration from the surface. The solar cell module has excellent external appearance and long-term durability.    DETAILED DESCRIPTION - A surface protection sheet and sealing material laminate comprises sealing material, surface protection sheet, and crystal nucleating agent. The sealing material has resin layer (a) containing silane modification ethylene-type resin (A) as outermost layer, and resin layer (b) containing ethylene-type resin (B) having crystal melting peak temperature of 100-145 degrees C and crystal melting heat quantity of 120-190 J/g when heated at a rate of 10 degrees C/minute measured by differential scanning calorimetry. The water-vapor-permeation rate of sealing material at 40 degrees C and 90 %RH is less than 3 g/m2.day. The surface protection sheet has an inorganic layer on the single surface of a base film, and moisture proof film having water-vapor-permeation rate at 40 degrees C and 90 %RH of less than 1 g/m2.day. An INDEPENDENT CLAIM is included for solar cell module.
