    摘要： Provided is a method of manufacturing a resin kneaded product in which an extrusion amount of a material can be increased and by which vent-up at an opening can be suppressed while spouting out of an unmelted material at the opening can be suppressed. A method of manufacturing a resin kneaded product includes kneading a material containing an additive (a) and a thermoplastic resin (b) using a twin screw extruder, in which the twin screw extruder is equipped with a supply port, a discharge port, an opening present between the supply port and the discharge port, a kneading section A present between the supply port and the opening, and a kneading section B present between the opening and the discharge port, a ratio L1 (La/D) of a length La of the kneading section A to a screw diameter D satisfies L1 ≥ 3, and the material is kneaded in the kneading section A without being completely filled and the material is also kneaded in the kneading section B.
