thermoplastic elastomer composition, injection molded product, sheet, automotive interior material, laminate, and instrument panel. It is an object of the present invention to provide a thermolpastic elastomer composition with high flowability of molding, mechanical and physical properties and wear resistance and to provide good appearance and feel, and molded products using it. a thermoplastic elastomer composition obtained by cross-linking a composition comprising: (a) 100 parts by weight of a polypropylene-based resin (b) from 80 to 200 parts by weight of a hydrogenated product of a block copolymer having at least one block mainly including a conjugated diene monomer unit and at least one block primarily including a vinyl aromatic monomer unit, (c) from 100 to 250 parts by weight of a softening agent, and (d) 5 to 20 parts by weight. polyorganosiloxane mass, the thermoplastic elastomer composition meeting the following conditions: (1) a content of the vinyl aromatic monomer unit in component (b) is 30 to 80% by mass (2) a melt flow rate (astm d1238) 230 198 c, load 1.2 kg; mfr) is 35 to 85 g / 10 min, (3) a hardness jis a is 60 to 90, (4) a permanent compression deformation (jis k6262 100 198 c, 22 hours) is 30 to 70%, and (5) a tensile elongation at -30 198 is not less than 80%.
