Provided is a molding die (10) comprising a die body (11) for molding a molded article (21) having an undercut part (20), and a demolding core (12) movable so as to approach and separate from the die body (11). When the demolding core (12) is separated from the die body (11), the demolding core (12) elastically deforms the molded article (21) such that the undercut part (20) separates from the die body (11), and makes it possible to remove the molded article (21) from the die body (11). The die body (11) comprises a recess (13) where the depth gradually reduces along the direction in which the demolding core (12) separates from the die body (11). During molding of the molded article (21), a projection (14) is formed on the undercut part (20) in accordance with the shape of the recess (13); during removal of the molded article (21), the engagement between the projection (14) and the recess (13) regulates the movement of the molded article (21) in a direction intersecting the movement direction of the demolding core (12). |
