A method is provided for producing a resin composition in which the fiber length of the fibrous filler contained in the resin composition is controlled. The method includes a step of feeding a resin (A) and a fibrous filler (B) to an extruder, melt-kneading and then extruding them. The extruder includes a cylinder, a screw mounted in the cylinder, a main feed port provided in the cylinder, and a side feed port provided rearwards from the main feed port in the extrusion direction. Part of the resin (A) and part of a fibrous filler (B) having a weight-average fiber length of not less than 1 mm are fed through the main feed port and the rest of the resin (A) and the rest of the fibrous filler (B) having a weight-average fiber length of not less than 1 mm are fed through the side feed port.
