A process for producing gaskets by curing a liquid molding material applied over a plate by a dispenser, wherein in order to improve accuracy in the cross-sectional shape and/or height of the gaskets, the process comprises the steps of: using a dispenser to coat the upper surface of a plate with a liquid molding material, and form a coating layer extending endlessly in a prescribed pattern; and overlapping a molding jig on the plate, the molding jig having in a lower surface a molding groove extending endlessly in a prescribed pattern corresponding to the coating layer, correcting the cross-sectional shape of the coating layer to a cross-sectional shape that corresponds to the molding groove, and curing the coating layer.
