Abstract

The present invention is related to a method for producing a resin composition including feeding a resin (A), a fibrous filler (B), and a particulate filler (C) which is harder than the fibrous filler (B) to an extruder, and melt-kneading to extrude a kneaded material, the resin composition comprising a fibrous filler (B) which is 140 μm or less in weight average fiber length. According to the present invention, a production method with high versatility is provided in which a resin composition containing the fibrous filler having the weight average fiber length of 140 μm or less is effectively produced.
