Claim 7:
8. A sealing material sheet for a solar-cell module, the sealing material sheet comprising:
a core layer containing a polyethylene-based resin; and
a skin layer containing a polyethylene-based resin and a silane-modified polyethylene-based resin,
wherein a whole resin component of the sealing material sheet contains:
