Abstract
A two-sided gasket is constituted of gasket bodies respectively provided on both surfaces of a base member in a thickness direction. The gasket has a structure in which one gasket body contributes to ensuring a seal surface pressure in an opposite gasket body, such that a configuration of the opposite gasket body and a method for forming the opposite gasket body are simplified. The gasket includes a base member, one gasket body that is provided on one side surface of the base member in the thickness direction, and an opposite gasket body that is provided on an opposite side surface of the base member in the thickness direction. The one gasket body includes a projection protruding toward the opposite side in the thickness direction. The base member includes a deformed portion protruding toward the opposite side in the thickness direction by covering the projection. The opposite gasket body is formed as a film-shaped rubber layer deposited on a front surface of the deformed portion.
