<P>PROBLEM TO BE SOLVED: To provide a method of molding a resin molding and a molding die which are used to mold a resin molding having an undercut by arranging a slide core and, prevent the generation of defective appearance by directing the degassing direction of a degassing structure arranged in the slide core to a direction opposite to the front surface side of the resin molding. Ž<P>SOLUTION: In the slide core 40 arranged in the core die 30 to mold an undercut, a long-and-narrow rod insertion hole 42 inserted with an oblique rod 41 is long enough to reach a degassing pin 44. The pin insertion hole 45 of the degassing pin 44 and the rod insertion hole 42 are made to communicate with each other, and clearances d1 and d2 are formed, respectively, between the degassing pin 44 and the pin insertion hole 45 and between the oblique rod 41 and the rod insertion hole 42. The configuration guides gas remaining in a cavity C during molding in a direction opposite to the front surface side of the resin molding 1 through the outer peripheral clearance d1 of the degassing pin 44 and the outer peripheral clearance d2 of the oblique rod 41, preventing the generation of the defective appearance.
