PROBLEM TO BE SOLVED: To provide an electrical contact material in which the increase in temperature caused by the instability of contact resistance in the conventional electrical contact material and the respective characteristics of deposition resistance, consumption resistance and workability are improved without using Cd in connection with an environmental problem. SOLUTION: The Ag-oxide-based electrical contact material used for a general-purpose switch controlling a load of an 80 to 300 V AC voltage and a 5 to 25 A rated current is composed of, by weight, 3.8 to 10.5% CuO and 1.0 to 6.0% ZnO, and the balance Ag.
