PROBLEM TO BE SOLVED: To provide a sealing material sheet for solar cell module capable of preventing degradation of a solar cell module due to crosslinking reaction gas derived from a crosslinking agent, while holding the features of a polyethylene-based resin, i.e., excellent steam barrier properties and insulation property.SOLUTION: In a sealing material sheet 1, a multilayer sheet having an intermediate layer 11 and an outermost layer 12, the intermediate layer 11 uses a mixed resin of low density polyethylene having a density of 0.870-0.910 g/cm, and a resin having a polar group as a base resin, where the polar group ratio of the mixed resin is 3%-15%, and the outermost layer 12 uses low density polyethylene as a base resin, but not containing a resin having a polar group. Total thickness of the multilayer sheet is 200-800 μm, and the thickness of the outermost layer 12 is 30-150 μm.SELECTED DRAWING: Figure 1 |
