PROBLEM TO BE SOLVED: To provide a polyarylene sulfide resin composition excellent in fluidity and mechanical strength, and suitably used for a molded article having a cylindrical part that is excellent in roundness. SOLUTION: The polyarylene sulfide resin composition comprises (A) a polyarylene sulfide resin having melt viscosity at a resin temperature of 310°C and at a shear rate of 1,200 sec<SP>-1</SP>of 10-50 Pa s, (B) a fibrous filler having an average fiber diameter of 15μm or less and (C) a non-fibrous filler, so that the amount Wf (wt.%) of the fibrous filler (B) and the amount Wm (wt.%) of the non-fibrous filler (C) in the composition satisfy formula (1): -Wf+45≤Wm≤-Wf+70 and formula (2): 0.4Wf≤Wm≤2.5Wf at the same time.
