PURPOSE: To obtain a polyphenylene sulfide resin composition excellent in forming cyclic peoperty during injection molding and useful for a connecter, a coil, sealing part, etc., by compounding a polyamide oligomer and a bisamide compound in a specific ratio.

CONSTITUTION: This composition is obtained by compounding (A) 100 pts.wt. of a polyphenylene sulfide resin with (B) 0.05-5 pts.wt. of the mixture of (i) a polyamide oligomer of the formula, R1CO(NHR2NHCOR3CO)nNHR4NHCOR5 [R1 and R5 are each a 10-40C monovalent organic group; R2 to R4 are each a 2-20C divalent organic group; (n)=1-30] and (ii) a bisamide of the formula, R6CONHR7NHCOR8 (R6 and R8 are each a 10-40C monovalent organic group; R7 is a 2-20C divalent organic group) in a ratio, component i/component ii, of 90/10 to 30/70 in terms of weight ratio.
