To provide a molding method of a resin molded product capable of preventing irregularity without forming a gap between a mold and a material to be molded even if the closure surface of the opening part of a cavity has a curved surface part when a molten resin is led out to be bonded to the closure surface, and the mold.
The molding method of the resin molded product includes a process for arranging the gap preventing member 15 so as not only to surround the opening part 13a of a cavity 13 but also to bring the closure surface 2a of the material 2 to be molded and the contact surface 14 on the side of the mold through the gap preventing member when the molten resin is introduced into the cavity 13, which is formed into a predetermined shape and has the opening part 13a, of the mold 10 from a nozzle through a communication port using the mold 10 and led out to the closure surface 2a of the material 2 to be molded, which is arranged so as to close the opening part, from the opening part to be integrated therewith, a process for introducing the molten resin into the cavity in a state that the opening part is closed by bringing the closure surface and the contact surface on the side of the mold into close contact with each other and a process for cooling and solidifying the introduced molten resin on the closure surface to integrally bond the same to the closure surface.
