Provided are: a thermoplastic elastomer composition having excellent mechanical characteristics and wear resistance; and a molded article comprising said thermoplastic elastomer composition. Specifically, a thermoplastic elastomer composition and a molded article comprising said thermoplastic elastomer composition are provided, said thermoplastic elastomer composition being obtained by heat treating, under melting conditions, a mixture containing: 100 parts by mass of at least one type of addition polymerization block copolymer (I) selected from a group consisting of a block copolymer and a hydrogenated product thereof, said block copolymer having a polymer block A mainly comprising an aromatic vinyl compound unit and containing at least 1% by mass of a structural unit (a) derived from a styrene having a C1-8 alkyl group bonded to a benzene ring and a polymer block B mainly comprising a conjugated diene compound unit; 10-300 parts by mass of an olefin resin (II); 0.01-20 parts by mass of a cross-linking agent (III); 1-50 parts by mass of a cross-linking agent (IV) having one methacryloyl group, one acryloyl group, and at least one hydroxyl group; and 30-250 parts by mass of a rubber-softening agent (V). |
