Abstract
Provided is a polyarylene sulfide resin composition of which the moldings are burred little and which has good mechanical properties and good flow moldability. The composition comprises from 20 to 90% by weight of a polyarylene sulfide and from 10 to 80% by weight of an inorganic filler, and is characterized in that its burrs are on the level of at most 120 &mgr;m, that it has a weld strength of at least 50 MPa and that the length of its spiral flow having a thickness of 1 mm is at least 100 mm. Preferably, the polyarylene sulfide to be in the composition has a specific index to the degree of branching and a specific flexural strength.
