Claims

[Scope of utility model registration request]

A gasket that is sandwiched between surfaces that face each other and are connected to maintain airtightness and liquidtightness between both surfaces, and is made by baking a rubber layer on at least one side of a metal plate around a through hole that allows fluid to pass through. A gasket made by crimping a seal plate to expose the rubber layer on the surface.
