ABSTRACT:
In an electric contact having a Cu-based layer, a Ni-based layer formed on the Cu-based layer, and a Pd-based layer formed on the Ni-based layer, the Ni-based layer having a thickness of at least 0.8 .mu.m is so formed as to include a noncrystal nickel alloy layer having a thickness of at least 0.08 .mu.m, in order to reduce the thickness of the Pd-based layer down to about 0.08 .mu.m, that is, the cost of the contact without deteriorating the contact durability, as compared with a 0.6 to 2 .mu.m thick prior-art Pd-based layer.
