Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing nitride/tungsten nanocomposite powder in which a nitride is uniformly dispersed into tungsten, and to provide nitride/tungsten nanocomposite powder produced by the method. SOLUTION: The method for producing nitride/tungsten nanocomposite powder comprises: a step where a nitride and tungsten are mixed or a nitride and a tungsten alloy are mixed; and a step where the mixture is subjected to mechanical alloying in an inert atmosphere using a milling machine.
