Thermoplastic elastomer composition, molded article thereof, and use thereof

The present invention addresses the problem of providing: a highly transparent thermoplastic elastomer composition which can be suitably used in applications such as interior skin materials without impairing the appearance (design properties such as texture moldability) and moldability of conventional interior skin materials; and a molded article thereof. The thermoplastic elastomer composition comprises 100 parts by mass of an ethylene-alpha-olefin-non-conjugated polyene copolymer (A), 20-5,000 parts by mass of a soft propylene copolymer (B) in which the melting point (TmB) is not observed or the melting point (TmB) is less than 115 DEG C, 10-500 parts by mass of a crystalline polyolefin (C) in which the melting point (TmC) is 115 DEG C or more, 0-70 parts by mass of a softening agent (D), and 0.01-10 parts by mass of a cross-linking agent (E). The soft propylene copolymer (B) further satisfies all of the following requirements (b-1) to (b-2): (b-1) the soft propylene copolymer contains 90-50 mol% of a propy
