An object of the present invention is to provide a thermoplastic elastomer composition having high molding fluidity, mechanical physical properties, and resistance to wear and providing a good appearance and feeling, and molded products using the same. A thermoplastic elastomer composition obtained by crosslinking a composition comprising: (A) 100 parts by mass of a polypropylene-based resin, (B) from 80 to 200 parts by mass 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 mainly including a vinyl aromatic monomer unit,(C) from 100 to 250 parts by mass of a softening agent, and (D) from 5 to 20 parts by mass of polyorganosiloxane, the thermoplastic elastomer composition satisfying conditions: (1) a content of the vinyl aromatic monomer unit in the component (B) is from 30 to 80% by mass, (2) a melt flow rate (ASTM D1238, 230°C, load of 1.2 kg; MFR) is from 35 to 85 g/10 min, (3) a JIS A hardness is from 60 to 90, (4) a compression set (JIS K6262, 100°C, 22 hours) is from 30 to 70%, and (5) a tensile elongation at -30°C is not less than 80%. |
