Abstract
A thermoplastic resin composition containing an olefin-based polymer and a hydrogenated block copolymer, wherein: with respect to the olefin-based polymer, an amount of heat of crystal fusion (ΔH) is less than 80 J/g; the hydrogenated block copolymer is a hydrogenated product of a block copolymer composed of a first polymer block consisting of a structural unit derived from an aromatic vinyl compound and a second polymer block consisting of a structural unit derived from a conjugated diene compound; the content of the first polymer block in the hydrogenated block copolymer is 1 to 60% by mass; a proportion of a vinyl bond amount of the second polymer block is 50 to 95 mol %; and the content of the hydrogenated block copolymer in the thermoplastic resin composition is from 1 to 30 parts by mass relative to 100 parts by mass of the total amount of the olefin-based polymer and the hydrogenated block copolymer.
