10 Claims

1. A resin composition comprising

an ethylene-vinyl acetate copolymer (I) and

a hydrogenated block copolymer (II), wherein the hydrogenated block copolymer (II) is a hydrogenated product of a block copolymer (P) containing

a polymer block (A) containing a structural unit derived from an aromatic vinyl compound and

a polymer block (B) containing

1 to 100% by mass of a structural unit (b1) derived from farnesene and

99 to 0% by mass of a structural unit (b2) derived from a conjugated diene other than farnesene,

wherein

the hydrogenation rate of carbon-carbon double bonds in the structural unit derived from a conjugated diene in the block copolymer (P) is 70 mol % or more,

in the resin composition, the content of the ethylene-vinyl acetate copolymer (I) is 40 to 95% by mass and the content of the hydrogenated block copolymer (II) is 5 to 60% by mass, and

the polymer block (A) has a peak top molecular weight of 5,000 to 100,000.
