Abstract

In a method producing a molded article of a composite resin containing base resin and fibers, the composite resin containing a fibrous filler in the base resin and the fibrous filler including natural fibers with a fibrillated part on each end of the fibrous filler in a fiber length direction, the base resin and the fibrous filler are charged into a melt-kneading device. The base resin is melted and the molten base resin and the fibrous filler are kneaded in the melt-kneading device, thereby fibrillating only the ends of the fibrous filler. The obtained composite resin is discharged from the melt-kneading device and formed into a pellet shape, with the molded article of the composite resin produced by molding the pellets.
