The port circumferential wall part (4) includes a resin part disposed along an inner surface thereof. The outer longitudinal rib (14) extends in a direction away from the intake-side wall part (1a) along a flow direction of intake air flowing inside the intake port (3). The boss part (13) includes a hole part (13a) that discharges gas in the intake port (3) when injection molding of the resin part is carried out.",
