PURPOSE:To obtain a casting gasket which has a proper elasticity capable of following volume shrinkage of casting resin in polymerization, maintains adhesion so as to joint the casting resin, has a proper peeling property with respect to the resin, and can be applied sufficiently widely to use of the casting resin which causes the volume shrinkage. CONSTITUTION:In a gasket to be mounted on a mating part of a plastic casting mold material, a polyorganosiloxane film 2 is formed at a part of the gasket which at least comes in contact with a casting resin 3. |
