Abstract: To provide a sealing material sheet for a solar-cell module that has high productivity, and can also suppress unevenness in thickness at the time of integration as a solar-cell module. There is provided a sealing material sheet 1 in which there are two inflection point temperatures that are temperatures only around which a change rate of the linear expansion coefficient locally increases, a first inflection point temperature at a low temperature side of two inflection point temperatures is within a range of 55° C. to 70° C., and a second inflection point at a high temperature side of the inflection point temperatures is within a range of 80° C. to 95° C.

Abstract: To provide a sealing material sheet for a solar-cell module that has high productivity without performing crosslinking processing, and has a high tensile shear adhesion force at normal temperature at a high level in addition to heat resistance and molding characteristics. A sealing material sheet is a multi-layer sheet using a polyethylene-based resin as a base resin, a core layer has a density of 0.880 g/cm3 to 0.895 g/cm3 and a melting point of 70° C. or higher, a skin layer has a density of 0.880 g/cm3 to 0.910 g/cm3 and a melting point of 90° C. or lower and contains a silane-modified polyethylene-based resin, a weight average molecular weight of the silane-modified polyethylene-based resin contained in the skin layer 11 in terms of polystyrene is 70000 to 120000, and a polymerized silane amount of the skin layer in the whole resin component is 300 ppm to 2000 ppm.
