The present invention is a thermoplastic elastomer composition containing 100 parts by mass of a hydrogenated block copolymer (a), 10 to 50 parts by mass of a polypropylene resin (b), and 5 to 100 parts by mass of a polyphenylene ether resin (c). 75-200 parts by mass of a non-aromatic softener (d), and the hydrogenated block copolymer (a) contains a hydrogenated block copolymer (a-1), and the hydrogenated block copolymer (a-1) ) Is hydrogenated and contains at least one polymer block A1 mainly composed of vinyl aromatic hydrocarbon compound monomer units and at least one polymer block B1 mainly composed of conjugated diene compound monomer units, The weight average molecular weight of the hydrogenated block copolymer (a-1) is 100,000 to 550,000, and the content of all vinyl aromatic hydrocarbon compound monomer units of the hydrogenated block copolymer (a-1) exceeds 20% by mass and 50 Mass% or less. |
