Abstract
There is provided a metal gasket that is less susceptible to lift and thrust phenomenon of housings and can effectively function as a sealing at a blowhole. The metal gasket includes an embossment portion provided with a pair of outer inclined portions and a pair of inner inclined portions. The metal gasket and satisfies the following relationships: Mh2/Mh1=1.10−1.81, W3>W1, and W3>W2, where Mh1 and Mh2 are vertical lengths, and W1, W2 and W3 are horizontal lengths. When the gasket is sandwiched in between two housings, tip ends abut on the housing to form two seal lines, and root ends, and another tip end abut on the housing H2 to form three seal lines.
