Summary:PROBLEM TO BE SOLVED: To carry out smooth form removal of an undercut-shaped molding.SOLUTION: In a molding apparatus 20, molding surfaces (FS2, FS3) have concave interference parts (IF1, IF2) which are arranged in the downstream of a molding 6P in the form removal direction and directed toward the inside of one mold, and relative motion of the molding 6P in the form removal direction is regulated by the interference of the interference parts (IF1, IF2) with parts of the molding (11a, 12a) molded in the interference part (IF1, IF2). In the interference parts (IF1, IF2), there are provided blowout parts (31a, 33a) capable of blowing out a gas toward the molding 6P.
