摘要

(A) containing a structural unit derived from an aromatic vinyl compound in an amount of 70 mol% or more and a structural unit derived from at least one member selected from the group consisting of a conjugated diene compound and isobutylene in an amount of 30 mol% A hydrogenated block copolymer having a polymer block (B), which satisfies the following conditions (1) and (2). Condition (1): the content of the polymer block (A) in the block copolymer is 1 to 30 mass%. Condition (2): When it is assumed that the polymer block (B) has a hydrogenation rate of 100 mol%, the main chain of the structural unit derived from at least one species selected from the group consisting of a conjugated diene compound and isobutylene The average value of the methylene chain length is 1.0 to 6.0.
