In the kneading extruder, the molten resin kneaded by the kneading screw is extruded by the gear pump; a flow path forming the resin flow path between the kneading screw and the gear pump; A volume adjustment piston is slidably supported by a wall and changes the volume of the resin flow path by moving in and out of the resin flow path in response to pressure within the resin flow path, and adjusting the volume. A kneading extruder equipped with a pressure fluctuation absorbing device, wherein a gas cylinder is attached to the outer end of the piston to elastically press the volume adjusting piston with a predetermined force in a direction to project into the resin flow path.
