Abstract
A heat-resistant gasket is provided with a first coating plate in which an annularly continuous emboss portion is formed and which is made of metal, a second coating plate which is arranged so as to face to the first coating plate in a thickness direction and is brought into close contact with a convex surface of the emboss portion, in which end portions in an inner peripheral side of the emboss portion are connected in a state of being in close contact with and lapped over the first coating plate and which is made of metal, and an expanded graphite core which is pinched between the first coating plate and the second coating plate, in a portion between the emboss portion and the overlapped portion of the end portions. Therefore, excellent sealing performance can be maintained even under a high-temperature environment while preventing stress relaxation due to heat.
