Claim 0:
1. A multilayer body comprising a base material (X), an adhesive layer (Y), and a base material (Z) in this order, wherein the adhesive layer (Y) contains a hydrogenated block copolymer (A) obtained by hydrogenating a block copolymer (P) containing a polymer block (a) composed of a structural unit derived from an aromatic vinyl compound and a polymer block (b) composed of a structural unit derived from a conjugated diene, the mass ratio [(a)/(b)] of the polymer block (a) to the polymer block (b) is 1/99 to 50/50, and the adhesive layer (Y) has a storage modulus G′ at 100° C. of 1.20×105 to 4.00×105 Pa;
wherein the polymer block (b) contains 1 to 100% by mass of a structural unit (b1) derived from farnesene and contains 0 to 99% by mass of a structural unit (b2) derived from a conjugated diene other than farnesene.
