Abstract
An object of the present disclosure is to provide a thermoplastic elastomer composition with good oil permeability resistance (oil impermeability). The present disclosure pertains to a thermoplastic elastomer composition containing an ethylene copolymer (A) having a weight-average molecular weight of 350,000 or more, a crystalline olefin polymer (B), a crosslinking agent (C), and a plasticizer (D), wherein the content of the plasticizer (D) is less than 130 parts by mass based on 100 parts by mass of the copolymer (A).
