NOVELTY - A sealing material sheet (1) has multilayer of intermediate layer (11) using polyethylene-type resin having density of 0.870-0.940 g/cm3, outermost layer (12) using polyethylene type resin having density of 0.870-0.900 g/cm3. The total thickness of the sheet is 300-1000 mu m. The thickness ratio of the intermediate layer and each outermost layer with respect to total thickness is 0.6-0.94, and 0.03-0.2, respectively. The torque value, measured at preset condition, of the intermediate layer and outermost layer is 0.11 N.m or more and less than 0.11 N.m, respectively.    USE - Sealing material sheet used for solar cell modules (claimed).    ADVANTAGE - The sealing material sheet has excellent water vapor barrier property, heat resistance and metal adhesiveness, and provides solar cell module with improved productivity.    DETAILED DESCRIPTION - A sealing material sheet has multilayer of intermediate layer using polyethylene-type resin (A1) having density of 0.870-0.940 g/cm3 as base resin, outermost layer using polyethylene type resin (B1) having density of 0.870-0.900 g/cm3 as base resin. The total thickness of the sheet is 300-1000 mu m. The thickness ratio of the intermediate layer and each outermost layer with respect to total thickness is 0.6-0.94, and 0.03-0.2, respectively. The torque value of the intermediate layer and outermost layer is 0.11 N.m or more and less than 0.11 N.m, respectively. The torque value is measured using a curelastometer based on JIS K6300-2 at 150 degrees C and plus minus 6 times/minute of torsional vibration number 100. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of sealing material sheet, which involves forming the intermediate layer by melt-molding the composition containing polyethylene type resin (A1) and 0-0.5 %mass cross-linking agent, laminating the outermost layer by melt-molding the composition containing polyethylene-type resin (B1) and 0-0.02 %mass cross-linking agent, molding un-bridged multilayer sheet, and performing crosslinking process by irradiation of ionizing radiation to the unbridged multilayer sheet; and    (2) solar cell module, which has the sealing material sheet and a solar cell component arranged such that the outermost layer of the sealing material sheet faces the metallic portion of the other component of the solar cell module.    DESCRIPTION OF DRAWING(S) - The drawing shows the schematic cross-sectional view of the sealing material sheet.    Sealing material sheet (1)    Intermediate layer (11)    Outermost layer (12)
