Patent ID: 8039555

Claim:
A thermoplastic resin composition comprising: a thermoplastic resin component (I) in an amount of 100 parts by mass; and a filler (II) in an amount of 200 to 900 parts by mass, wherein the thermoplastic resin component (I) comprises: a block copolymer (A) in an amount of 5 to 90 mass %, the block copolymer (A) being at least one species selected from the group consisting of a block copolymer and a hydrogenated product thereof, the block copolymer having a polymer block (a1) comprising an aromatic vinyl compound unit(s) and a polymer block (a2) comprising a conjugated diene unit(s); a polyolefin resin (B) in an amount of 5 to 90 mass %; and a block copolymer (C) in an amount of 5 to 90 mass %, the block copolymer (C) having a polymer block formed from a repeating unit having a polar group, wherein the block copolymer (C) is a first block copolymer (C-1) or a second block copolymer (C-2), wherein the first block copolymer (C-1) is a block copolymer comprising a polymer block (c1) and a polymer block (c2), the polymer block (c1) being selected from the group consisting of a polyurethane polymer block, a polyester polymer block, a polyamide polymer block, a polycarbonate polymer block, and a (meth)acrylic acid ester polymer block, and the polymer block (c2) comprising at least one block copolymer selected from the group consisting of a block copolymer having a polymer block comprising an aromatic vinyl compound unit(s) and a polymer block comprising a conjugated diene unit(s) and a hydrogenated product thereof, and the second block copolymer (C-2) is a (meth)acrylic acid ester block copolymer having a first (meth)acrylic acid ester polymer block, and a second (meth)acrylic acid ester polymer block which is different from the first (meth)acrylic acid ester polymer block.
