To effectively prevent a breakage of a plate (1) when a gasket body formed of a rubber-like elastic material is integrally molded at both faces of the plate formed of a brittle material such as carbon. In order to attain this object, there is provided a method of manufacturing a plate-integrated gasket in which a gasket body formed of a rubber-like elastic material is integrally formed at both sides of a portion along a peripheral edge of a plate (1) in the thickness direction, where an area (15) located between gasket molding cavities (23, 24) defined by clamping the plate (1) between split dies (21, 22) of a metal mold (2) in the plate (1) is formed to be a relatively thick portion (15a) at a position, facing an opening (25a) of a gate (25) through which a molding material is injected into the cavities (23, 24), and in the vicinity thereof.
