PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition which can give excellent chemical resistance to an ABS resin by mixing five components including a specified copolymer and a resin. SOLUTION: This composition comprises 3-50 pts.wt. maleimide copolymer (A) comprising residues of an aromatic vinyl monomer, residues of an unsaturated dicarboxylic acid anhydride, residues of an unsaturated dicarboxylic acid imide derivative, etc., 0-50 pts.wt. vinyl copolymer (B) comprising residues of an aromatic vinyl monomer, residues of a vinyl cyanide monomer, etc., 3-50 pts.wt. graft copolymer (C) prepared by grafting a monomer mixture comprising an aromatic vinyl monomer, a vinyl cyanide monomer, etc., onto a rubbery polymer, 20-56 pts.wt. polyamide resin (D) and 12-40 pts.wt. elastomer copolymer (E) comprising an ethylene/α-olefin copolymer containing residues of an unsaturated dicarboxylic acid monomer and/or residues of its acid anhydride monomer (the total of components A to E is 100 pts.wt.).
