Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain an Ag-oxide electric contactor material having excellent contact reliability, welding resistance and arc consumption resistance and used for various switches, contactors, breakers, or the like, and also to provide its manufacturing method. SOLUTION: An internally oxidizable Ag alloy prepared under the condition of 50-95% cold draft is subjected, after replacing the air in a pressurized oxidation furnace with oxygen, to temperature-raise gradually from
