Process for producing foam moldings with an insert executed in a mold for foam molding consisting of a core block and a cavity block. The process comprises steps of: (a) having a film adhering to and covering the insert on one side thereof where a foam layer is formed; (b) letting the skirt portion of the film to be pinched or sandwiched by the uniting portion of the two blocks while the foaming process is executed on a foamable material; and (c) forming integrally the foam layer on that side of the insert, with the film being retained between the insert and the foam layer to be obtained.
