A thermoplastic resin composition capable of providing a molded article which is inhibited from making rattling noise and preferably has high rigidity is provided, which comprises a rubber-reinforced resin (A) having a rubber portion (a1) derived from a block copolymer, or hydrogenated product thereof; and a resin portion (a2) comprising a structural unit derived from an aromatic vinyl compound. The block copolymer includes a block (I) having a structural unit derived from an aromatic vinyl compound, and a block (II) having a structural unit derived from isoprene or from isoprene and butadiene, and having a main dispersion peak of tan δ at no less than 0° C. The thermoplastic resin composition has a maximum value of sound pressure of 3.0 Pa/N or less over a frequency range of 20-20,000 Hz measured under predetermined conditions. |
