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 (20f) 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.
