본 발명은 수지 필름으로 이루어지는 보강체와, 보강체의 두께 방향 일방(一方)의 면측에 설치된 일면측 개스킷 본체와, 보강체의 두께 방향 타방(他方)의 면측에 설치된 타면측 개스킷 본체를 구비하고, 보강체는, 양 개스킷 본체에 끼인 부분에, 수지 필름을 그 두께 방향으로 굴곡시킨 입체 형상을 구비하는 것을 특징으로 한다. 일면측 개스킷 본체는, 타면측 개스킷 본체를 향해 돌출하는 역 테이퍼 형상의 걸림결합 볼록부를 구비하고, 보강체는, 걸림결합 볼록부의 형상을 따라 변형된 입체 형상으로서의 변형부를 구비하며, 타면측 개스킷 본체는, 걸림결합 볼록부 및 변형부를 매설하는 역 테이퍼 형상의 걸림결합 오목부를 구비하는 것을 특징으로 한다. 또, 일면측 개스킷 본체 및 타면측 개스킷 본체 중 적어도 일방(一方)의 개스킷 본체는, 평탄면 형상의 시일(seal) 면을 구비하며, 보강체는, 평탄면 형상의 시일 면을 향해 돌출하는 입체 형상으로서의 볼록 형상을 구비하는 것을 특징으로 한다. The present invention is characterized by being provided with a reinforcing body that is made of a resin film, a one-side gasket body that is provided on one surface of the reinforcing body in a thickness direction thereof, and another-side gasket body that is provided on another surface of the reinforcing body in the thickness direction, wherein the reinforcing body has, in a portion sandwiched between both the gasket bodies, a three-dimensional shape in which the resin film is bent in its thickness direction. The one-side gasket body includes an inversely-tapered engaging convex portion that protrudes toward the other-side gasket body, the reinforcing body includes a deformation portion as the three-dimensional shape that is deformed along a shape of the engaging convex portion, and the other-side gasket body includes an inversely-tapered engaging concave portion that embeds therein the engaging convex portion and the deformation portion. Moreover, at least one gasket body 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 that protrudes toward the flat surface-shaped seal surface.
