PROBLEM TO BE SOLVED: To provide a sealing material composition for a sealing material sheet, excellent in extrusion suppressing effect during vacuum heat lamination, the sealing material sheet being used for a solar cell module and comprising a polyethylene based resin with a crosslinking agent, as a base.SOLUTION: A sealing material sheet is obtained by melt molding a composition containing a polyethylene based resin (A) having a MFR of 25 g/10 min or more and 40 g/10 min or less, a polyethylene based resin (B) having a MFR of 1 g/10 min or more and 3 g/10 min or less, and a cross linking agent (C), while a mass ratio between the polyethylene based resin (A) and the polyethylene based resin (B) is from 90:10 to 75:25. Here, the polyethylene based resin (B) having a relatively low MFR exhibits fluidity inhibiting effect, thereby solving the problems. |
