Claims

[Scope of utility model registration request]

forming a first through-hole sealing part by the through-hole forming folded part of the first layer member and the vertical annular elastic part of the multilayer plate-like overlapping member;
A required distance is placed outside the outer periphery of the folded portion for forming the through hole,
and an annular member is interposed between the multilayer plate-like polymerized members, and the thickness of the second through hole sealing portion formed by the annular member, the multilayer plate-like polymerized member, and the first layer member is set to the thickness of the first through hole. The thickness is smaller than the thickness of the sealing part, and larger than the sum of the thicknesses of the multilayer plate-like polymeric member and the first layer member located between the first through-hole sealing part and the second through-hole sealing part. A laminated gasket formed as follows.
