摘要： There is provided a screw rotor that can ensure safe rotation and can greatly increase a pumping performance of a pump. The screw rotor is placed with a gap between a top end surface of a tooth of a screw portion and an inner wall surface of a stator. A PFA film is provided on the top end surface. If the PFA film of the present invention is provided in a predetermined manner, the width of a gap between a free surface of the PFA film and the inner wall surface of the stator can be made significantly smaller than that of a conventional one, so that the pumping performance is greatly improved. After coating at least the top end surface of the screw rotor with PFA, followed by melting and remelting processes, the PFA film is formed to have a high smoothness on its free surface.
