PROBLEM TO BE SOLVED: To obtain a composition which is excellent in stiffness, toughness, moldability, electric characteristics and the like and useful for formation of parts for power supply by blending specific amounts of a polyphenylene sulfide resin, a potassium titanate fiber, a carbon fiber and a platy filler. SOLUTION: 40-65 wt.% (hereinafter referred to as %) of a polyphenylene sulfide resin, 25-45% of a potassium titanate fiber which preferably has an average fiber diameter of 3μm or less, an average fiber length of 5-200μm and an aspect ratio of 10 or more, 5-10% of a carbon fiber which has a fiber diameter of 7-20μm and a fiber length of 0.1-6 mm and 5-10% of a platy filler which preferably has an average aspect ratio of 80 or less and an average flake diameter of 30μm or less are blended. The platy filler is preferably mica. The polyphenylene sulfide resin composition preferably has a flexural modulus of 20 GPa or more (according to ASTM D790) and a volume resistivity value of 106Ω.cm or more.
