Provided is a metal gasket that can comply with reduced engine size and weight and increased displacement. This metal gasket is divided into the following three regions from the side of a combustion chamber hole (7) toward the outer peripheral side of the gasket: a first region (R1) from the edge of the combustion chamber hole (7) to a position in the middle of the width direction of a combustion chamber hole-side bead (2); a second region (R2) from said position in the middle of the width direction of the combustion chamber hole-side bead (2) to a position in the middle of a position overlapping a cooling water region (W/J); and a third region (R3) more toward the outer peripheral side than the second region (R2). The plate thickness of the metal gasket (20) is constructed such that the first region (R1) is the thickest, the second region (R2) is the second thickest, and the third region (R3) is the thinnest. This plate thickness is constructed by an auxiliary plate (4). |
