The purpose of the present invention is to improve the handling and usability of rubber only-type gaskets. To achieve said purpose, a gasket molding is obtained by combining a rubber only-type gasket body with a film carrier obtained from a resin film that holds the gasket body in an unbonded state. The gasket molding is characterized in that: in addition to a gasket-holding section for holding the gasket body, the film carrier has temporary tacking sections that are surface-treated to temporarily tack the gasket body to said film carrier; the gasket body has temporary tack-receiving sections that are temporarily tacked to the temporary tacking sections; and the temporary tacking sections and temporary tack-receiving sections are removed from the film carrier and the gasket body when the film carrier and gasket body are punched into the product shapes.
