1. A self-piercing rivet that fastens a plurality of fastened members by being driven into an overlapping part of the fastened members, the self-piercing rivet comprising:
a head;
an outer cylindrical part that extends from the head, that is provided in a cylindrical shape, and in which a tip side deforms radially outward when driven into the overlapping part; and
an inner cylindrical part that extends from the head and provided in an inner side of the outer cylindrical part while being distanced from the outer cylindrical part, that is provided in a cylindrical shape, and in which a tip side deforms radially outward or radially inward when driven into the overlapping part,
wherein a tip part of the outer cylindrical part is provided with an inclined inner surface in which an inner diameter is gradually increased toward the tip side, and a tip part of the inner cylindrical part is provided with an inclined outer surface in which an outer diameter is gradually decreased toward the tip side.
