PROBLEM TO BE SOLVED: To eliminate defective moldings or the like in a seal part adhered to a waterproof connector housing. SOLUTION: In a method for injection-molding a female die housing 1 by a housing molding die, leaving a hood part periphery molding die 14 comprising a part of the housing molding die, replacing other die parts with a seal part molding rear die 20 and front die 21, and integrally adhering the seal part to the female die housing, the female die housing 1 is opened toward a seal part molding space 26 by the front die 21 to provide an inflow opening 8 and an outflow opening 9 of a rubber material, and also the cross sectional area of the outflow 8 is formed smaller to increase flow resistance of the rubber material. By means of communicating an inflow passage 6 with an outflow passage 9, and communicating the inflow opening 8 with the outflow opening 9, the rubber material is consecutively filled from the inflow passage 6 of the rear die 20 through the inflow opening 8 into the seal part molding space 26, and further filled through the outflow opening 9 into the outflow passage 7.
