PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition comprising polycarbonate copolymer and styrene based resin excellent in wet heat fatigue resistance, wet heat strength retention while maintaining impact strength, moldability or the like that the polycarbonate copolymer and polystyrene originally have. SOLUTION: This thermoplastic resin composition comprises (A) 1-99 wt.%. polycarbonate copolymer comprising at least 80 mol% of the whole aromatic dihydroxy compounds comprising (a) 1,1-bis(4-hydroxylphenyl)-3,3, 5- trimethylcyclohexane (component (a)) and (b) 4,4-(m-phenylene-diisopropylidene) diphenol and/or 2,2-bis(4-hydroxy-3-methylphenyl)propane (component (b)), the molar ratio of the component (a), (b) being 99:1-20:80 and (B) 99-1 wt.%. styrene based resin.
