Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power supply die for preventing impurities from sticking even when the die is used for wire electric discharge machine causing discharge in a working liquid such as ion exchange water. SOLUTION: The power supply die for the wire electric discharge machine includes a body made of cemented carbide and an organic insulating film uniformly coating the body. The carbon amount regarding the total weight of four elements of tungsten, cobalt, carbon and oxygen is 2.8-16 wt.% when energy dispersion type X-ray analysis is executed with acceleration voltage of 15 kV.
