1. A rivet joining method for providing joining after a rivet is inserted into a hole formed in a base member, wherein the base member comprises a plurality of members,
wherein the hole is formed such that it passes through at least one from among the members and the hole has a metal side wall,
wherein the rivet is formed of a metal material and has a head portion and a body portion,
wherein the rivet joining method comprises joining processing in which a vibration processing part applies sound vibration and/or ultrasound vibration to the rivet in a state in which at least the body portion is inserted into the hole, so as to join the rivet and the metal side wall of the hole, and
wherein the joining processing is performed using diffusion of atoms that occurs between the rivet and the hole.
