PURPOSE: To obtain a composition for load-dispatching part excellent in dielectric breakdown voltage characteristics and mechanical characteristics and useful for sockets, etc., by compounding a polyamide resin, talc, a hindered phenol antioxidant, and an organic phosphorus stabilizer in a specific ratio. CONSTITUTION: This composition comprises (A) 60-80 pts.wt. polyamide resin (e.g. nylon 6), (B) 40-20 pts.wt. talc having an average particle diameter of <=2μm, (C) a hindered antioxidant [e.g. triethylene glycol bis(3-(3-t-butyl-5- methyl-4-hydroxyphenyl)propionate)] in an amount of 0.05-2wt.% based on the component A, and (D) an organic phosphorus stabilizer [e.g. tris(2,4-di-t- butylphenyl) phosphite] in an amount of 0.3-1wt.% based on the component A.
