PROBLEM TO BE SOLVED: To provide a seal member which securely seals a seal attachment part with heat resistance and durability enhanced. SOLUTION: The seal member 2 disposed in a position around a high-temperature space includes: a main body 20 formed by a metal thin plate and provided with a roughly center part in a plain view being curved in a convex shape on one side; and a side part 21 provided with cross-sectional R-shaped continuous faces 24a and 24b along the edge part of the main body 20. When it is attached to a mounting hole 17 drilled in a cylinder block 10, it is pressed from a convex side face 20a of the main body 20, and the side part 21 is welded with pressure to the inner wall 17d of the mounting hole 17 in a biassing direction and also to the inner wall 17e of the mounting hole 17 in a direction orthogonal to the biassing direction.
