A thermoplastic elastomer composition includes a hydrogenated block copolymer, which is obtained by hydrogenating a block copolymer having two or more polymer blocks (a) each containing a structural unit derived from an aromatic vinyl compound and one or more polymer blocks (b) each containing structural units derived from isoprene and 1,3-butadiene, a thermoplastic resin, and a rubber softener. The hydrogenated block copolymer has a crystallization peak temperature (Tc) of −3 to 15° C.
