。[Claims for Utility Model Registration] (1) A pure silver layer with a thickness of 5 to 40% of the thickness between at least two layers of a silver alloy with a predetermined thickness and containing 0.5 to 12% by weight of Sn. Completely internally oxidize the composite formed in one piece, cut this completely internally oxidized composite into two horizontally around the pure silver layer, and weld the pure silver layer to the contact base metal. Ag-- with no cracks on the outer surface of the contact surface.
SnO-based electrical contact material. (2) The pure silver layer is internally oxidized by interposing a thin plate of Fe, Ni, etc., which cannot be internally oxidized and forms an oxide film on the surface during oxidation, as two layers, and after internal oxidation, both sides of this thin plate are coated. The Ag--SnO-based electrical contact material according to claim 1, which is obtained by peeling and cutting the composite into two laterally.
