Zusammenfassung:	PURPOSE:To obtain a polyarylene sulfide resin composition with prevented coloring in melt molding capable of providing pellets having a high whiteness degree by adding a 3,4,5,6dibenzo-1,2-oxaphosphane-2-oxide to a polyarylene sulfide resin. CONSTITUTION:A polyarylene sulfide resin composition obtained by adding (B) 0.05-5 pts.wt., preferably 0.1-1 pt.wt. 3,4,5,6-dibenzo-1,2-oxaphosphane-2-oxide to (A) 100 pts.wt. polyarylene sulfide resin, preferably polyphenylene sulfide resin, prepared by carrying out polymerization using an organic amide solvent as a polymerization medium and having preferably
