PROBLEM TO BE SOLVED: To obtain a thermoplastic resin composition excellent in reliability of humidity resistance and moldability by compounding a straight-chain polyarylene sulfide resin with an inorganic ion exchanger, a specified ethylene copolymer, and an inorganic filler. SOLUTION: This composition comprises a straight-chain polyarylene sulfide resin, desirably, a poly-p-phenylene sulfide comprising at least 70 wt.% p- phenylene sulfide units; an inorganic ion exchanger; an ethylene copolymer comprising ethylene, an alkylα,β-unsaturated carboxylate, and maleic anhydride; and an inorganic filler. The ethylene copolymer is desirably the one comprising 50-90 wt.% ethylene, 3-49 wt.% alkylα,β-unsaturated carboxylate, and 0.5-10 wt.% maleic anhydride, The inorganic ion exchanger is desirably the one represented by the formula: SbaBibOc(OH)d(NO3)e.nH2O (wherein (a) and (b) are each 1-2; (c) is 1-7; (d) is 0.2-3; (e) is 0.05-3; and (n) is 0-2).
