Abstract
The present invention is a rivet contact including a head portion and a foot portion having a smaller width than the head portion, wherein the head portion contains a contact material layer having at least a top containing an Ag-based contact material; the rest of the head portion and the foot portion contain a base material containing Cu or a Cu alloy; and a barrier layer including an Ag alloy is provided at a junction interface between the contact material and the base material. Here, an Ag alloy obtained in such a manner that one or more base metal elements of Sn, In, Cu, Ni, Fe, Co, W, Mo, Zn, Cd, Te, and Bi are added to Ag by 0.03 to 20 mass % is preferably used as the Ag alloy constituting the barrier layer.
