Abstract
In a method for producing a molded gasket having a surface treated layer on one surface of a substrate and integrally formed with a gasket body constructed by a rubber-like elastic body on the other surface, a first step of integrally molding the gasket body on the substrate, a second step of temporarily placing the molded piece on a placement stand, and a third step of removing a burr portion from a production portion by punching the molded piece are sequentially executed. For preventing foreign material attachment, pollution and scratching, the first step integrally forms a projecting leg portion constructed by a rubber-like elastic body at a position corresponding to the burr portion in the molded piece, the second step brings the molded piece into contact with the placement stand by the leg portion, and the third step removes the leg portion as a part of the burr portion.
