A gasket to be placed in an annular groove includes an annular base to be placed in the groove, and a plurality of protrusions arranged at intervals on the base in a circumferential direction of the base. The protrusions protrude from the base to face side surfaces of the groove and have support surfaces with curvatures corresponding to curvatures of the side surfaces of the groove. Each protrusion has a length in the circumferential direction greater than an interval between facing ends of adjacent ones of the protrusions in the circumferential direction.
