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 (1) with a liquid molding material, and form a coating layer (20) extending endlessly in a prescribed pattern; and overlapping a molding jig (3) on the plate (1), the molding jig (3) having in a lower surface (3a) a molding groove (31) extending endlessly in a prescribed pattern corresponding to the coating layer (20), correcting the cross-sectional shape of the coating layer (20) to a cross-sectional shape that corresponds to the molding groove (31), and curing the coating layer (20).
