FILM-INTEGRATED GASKET

A film-integrated gasket is provided in which a gasket body is supported by a gasket support body formed of a resin film and a film thickness tat a position where the gasket body is supported is set to be smaller than a film thickness tat an adjacent position thereto so as to satisfy a demand for low reaction force by reducing the compression ratio in the thickness directional in mounting. The film-integrated gasket can be provided with a portion compressed in the thickness direction at the position where the gasket body is supported, so that the portion sets a thickness difference. The film-integrated gasket can alternatively be provided with a portion where a plurality of resin films is stacked at an adjacent position to the position where the gasket main body is supported, so that the portion sets a thickness difference.
