PROBLEM TO BE SOLVED: To provide a method for manufacturing a powder of an alloy consisting of refractory metals and containing a reduced amount of oxygen in particular, and to provide the fine powder of the alloy consisting of the refractory metals and containing a small amount of oxygen. SOLUTION: The method for manufacturing the fine powder of an alloy comprises the steps of: compounding two or more refractory metal elements having a melting point of 1,600°C or higher into a complex metal; melting it in high-temperature plasma containing a reducing gas; and rapidly solidifying the molten complex metal into the powder of the alloy. The fine powder of the alloy consists of two or more refractory metal elements having a melting point of 1,600°C or higher has a melted and solidified structure, has a particle diameter of 500μm or larger and has an oxygen content controlled to 500 ppm or less.
