Abstract
A gasket includes a reinforcing body made of a resin film, a one-side gasket body on one surface of the reinforcing body, and another-side gasket body on another surface of the reinforcing body. The reinforcing body has, between both gasket bodies, a three-dimensional shape in which the resin film is bent. The one-side gasket body includes an inversely-tapered engaging convex portion protruding toward the other-side gasket body, the reinforcing body includes a deformation portion as the three-dimensional shape deforming along a shape of the engaging convex portion, and the other-side gasket body includes an inversely-tapered engaging concave portion embedding therein the engaging convex portion and the deformation portion. At least one of the one-side gasket body and the other-side gasket body includes a flat surface-shaped seal surface, and the reinforcing body has a convex shape as the three-dimensional shape protruding toward the flat surface-shaped seal surface.
