An olefinic thermoplastic elastomer foam or an olefinic thermoplastic elastomer foam laminate having excellent moldability, heat resistance, scratch resistance, abrasion resistance and flexibility balance is provided. An olefinic thermoplastic elastomer composition comprising a syndiotactic α-olefin copolymer (a) or a syndiotactic α-olefin copolymer (a) and another thermoplastic resin (b). (A), the density ρ of the foam is in the range of less than 700 kg / m 3 , and the compression set Cs after the foam is compressed by 50% and kept in an oven at 70 ° C. for 22 hours is less than 60%. Thermoplastic elastomer foam (B). [Selection] Figure 2 |
