Abstract
A gasket formed by laminating two or more metal plates includes a seal target hole, an annular seal portion sealing an outer peripheral edge of the seal target hole, and a plurality of bolt holes disposed at the outer peripheral side of the seal portion. Each metal plate constituting a thermal deformation coping portion is provided with slits intersecting in a longitudinal direction of the metal plate and each slit constitutes a lamination portion of the metal plate so as not to penetrate in a lamination direction. When one seal target hole is provided, a portion suspended in the seal target hole is formed at the thermal deformation coping portion, and when multiple seal target holes are provided, at least one of portions interposed between the adjacent seal portions and a portion interposed between the adjacent bolt holes is formed at the thermal deformation coping portion.
