Provided are a resin composition, a pellet, a veil, a vibration damping material, a sound insulator, and an intermediate film for laminated glass, each of which is much more excellent in damping properties. Specifically, the resin composition is a resin composition containing the following block copolymer or hydrogenation product thereof (X); and a tackifier resin (Y) having a glass transition temperature of −50 to 45° C., wherein when a glass transition temperature of a polymer block (B) of the block copolymer or hydrogenation product thereof (X) is designated as Tg(X), and a glass transition temperature of the tackifier resin (Y) is designated as Tg(Y), an absolute value of a difference between Tg(X) and Tg(Y) is 50° C. or lower, the block copolymer or hydrogenation product thereof (X) being a block copolymer or a hydrogenation product thereof having a polymer block (A) containing more than 70 mol % 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, and the content of the polymer block (A) in the block copolymer being 25% by mass or less.
A resin composition comprising a block copolymer or hydrogenation product thereof (X);
