1. A laminate, comprising:
an X layer comprising a hydrogenated block copolymer; and
a plurality of Y layers laminated on at least one surface of the X layer;
wherein the hydrogenated block copolymer is a hydrogenation product of a block copolymer comprising a polymer block (A) consisting of a structural unit derived from an aromatic vinyl compound and a polymer block (B) containing 30 mol % or more of a structural unit derived from at least one selected from the group consisting of a conjugated diene compound and isobutylene,
when the polymer block (B) is regarded as having a structure with a hydrogenation rate of 100 mol %, an average value of a methylene chain length of a main chain of the structural unit derived from at least one selected from the group consisting of a conjugated diene compound and isobutylene is from 1.0 to 6.0;
wherein at least one of the plural Y layers is a layer comprising a thermoplastic resin (different from the hydrogenated block copolymer, and
the thermoplastic resin (i) is an ionomer or a polyvinyl acetal resin.
