To provide an injection molded pipe member having a high quality, the pipe member is integrally provided with a holder portion ( 20 ), a pipe portion ( 30 ) and ribs ( 40 ) arranged in an outer periphery of the pipe portion ( 30 ) at a uniform interval in peripheral direction, protruding in radial direction and reaching the holder portion ( 20 ) from a middle of the pipe portion ( 30 ), and has a resin injecting position ( 20 f) in a surface of a portion except the pipe portion ( 30 ) and the ribs ( 40 ), so that molten resin flows quickly through the forming space uniformly in peripheral direction without being deflected when injection molding, thereby bend of the pipe portion ( 30 ), thickness shrink, and forming die breakage is prevented.
