摘要： A kneading segment 1A according to the present invention is provided in each of a pair of kneading screws rotatably accommodated in a barrel 2 having a cavity therein and rotates in the same direction along with the kneading screw so as to knead a material supplied into the barrel 2, wherein the kneading segment includes at least two kneading flights 11A protruding outward in the radial direction, and a ratio of a root diameter with respect to the curvature radius of the cavity of the barrel 2 is 0.6 or less. According to the present invention, it is possible to obtain the kneading segment that increases a flow having a high elongation degree.
