摘要：
A sheet for solar cell encapsulant including (A) an ethylene copolymer selected from 1a to 5a; and (B) an ethylene copolymer selected from 1b to 3b, the copolymer (A) having a melting point of 90° C. or higher and containing constituent unit derived from ethylene [1a: ethylene-vinyl acetate (VA) copolymer, 2a: ethylene-acrylate copolymer, 3a: high-pressure method low-density polyethylene, 4a: ethylene-α-olefin copolymer, 5a: ethylene-G(M)A copolymer other than the below-described 1b, 1b: ethylene-G(M)A copolymer, 2b: ethylene-VA-G(M)A copolymer, 3b: ethylene-acrylate-G(M)A copolymer]. In the ethylene copolymer (B), the total ratio of the constituent unit derived from glycidyl(meth)acrylate (G(M)A) is preferably from 2% to 30% by mass. As a result of this, crosslinking treatment is substantially unnecessary, and practical adhesion and adhesion stability are achieved without heat treatment for crosslinking.
