A gasket which is annular, which is to be interposed between a first flange of a first exhaust pipe and a second flange of a second exhaust pipe in a state where the gasket is fitted onto an end portion of the first exhaust pipe, in order to seal a gap between the end portion of the first exhaust pipe and an end portion of the second exhaust pipe, the gasket being configured by using an expanded graphite tape and a metal mesh member, wherein the gasket includes: a first sealing portion having: a first butting surface having a tapered shape corresponding to a tapered shape of a first tapered inner circumferential surface of the first flange in which a diameter is gradually increased as proceeding toward the second flange; and a first projecting portion which is projectable toward the first tapered inner circumferential surface as compared with the first butting surface, the first sealing portion being formed in a radially outer side so as to allow the first butting surface and the first projecting portion to butt against the first tapered inner circumferential surface, wherein the first projecting portion has a first projecting end portion formed in a pointed shape and located radially outside the first butting surface; and a second sealing portion having: a second butting surface having a tapered shape corresponding to a tapered shape of a second tapered inner circumferential surface of the second flange in which a diameter is gradually increased as proceeding toward the first flange; and a second projecting portion which is projectable toward the second tapered inner circumferential surface as compared with the second butting surface, the second sealing portion being formed in a radially outer side so as to allow the second butting surface and the second projecting portion to butt against the second tapered inner circumferential surface, wherein the second projecting portion has a second projecting end portion formed in a pointed shape and located radially outside the second butting surface, wherein the first projecting end portion is separate from the second projecting end portion. a first sealing portion having: a first butting surface having a tapered shape corresponding to a tapered shape of a first tapered inner circumferential surface of the first flange in which a diameter is gradually increased as proceeding toward the second flange; and a first projecting portion which is projectable toward the first tapered inner circumferential surface as compared with the first butting surface, the first sealing portion being formed in a radially outer side so as to allow the first butting surface and the first projecting portion to butt against the first tapered inner circumferential surface, wherein the first projecting portion has a first projecting end portion formed in a pointed shape and located radially outside the first butting surface; and a second sealing portion having: a second butting surface having a tapered shape corresponding to a tapered shape of a second tapered inner circumferential surface of the second flange in which a diameter is gradually increased as proceeding toward the first flange; and a second projecting portion which is projectable toward the second tapered inner circumferential surface as compared with the second butting surface, the second sealing portion being formed in a radially outer side so as to allow the second butting surface and the second projecting portion to butt against the second tapered inner circumferential surface, wherein the second projecting portion has a second projecting end portion formed in a pointed shape and located radially outside the second butting surface,
