Provided is a thermoplastic elastomer composition, wherein a specimen having a size of 30 mm wide × 30 mm long × 2.0 mm thick punched out from a central portion of a molded article formed by injection-molding the thermoplastic elastomer composition into a mold cavity, 90 mm wide × 150 mm long × 2.0 mm thick, under conditions of a cylinder temperature of 220°C, a mold temperature of 50°C, and an injection rate of 25 cm3/sec satisfies the following requirements (1) and (2), Requirement (1): an area increase rate S of the specimen after impregnation with petroleum benzine at 23°C for 24 hours is 20% or less; and Requirement (2): a volume increase rate V of the specimen after impregnation with petroleum benzine at 23°C for 24 hours is 20% or more and 125% or less.",
