Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a thermoplastic elastomer composition and a thermoplastic elastomer composition powder excellent in handleability, fluidity at the time of processing and molding, grain transferability and a skin material, composed thereof and excellent in mechanical characteristics, heat resistance and designability. SOLUTION: This thermoplastic elastomer composition comprises (A) 10-70 wt.% styrene-based thermoplastic elastomer, (B) 10-50 wt.% ethylene-α-olefin copolymer having 20-200 g/10 min melt flow rate at 190 deg.C and 0.865-0.919 g/cm density, (C) 10-50 wt.% ethylene-α-olefin copolymer having 20-200 g/10 min melt flow rate at 190 deg.C and 0.920-0.945 g/cm density and (D) 3-25 wt.% crystalline polypropylene resin.
