Abstract
The invention provides a method for producing a sputtering target material including electrolyzing a molten salt mixture containing a precious metal salt and a solvent salt, to thereby deposit a precious metal or a precious metal alloy. The method enables simplification of production steps and produces high-purity target materials. In addition, the electrodeposited precious metal or precious metal alloy is heat-treated at a temperature of at least 800° C. but lower than the melting point of the precious metal, to thereby produce a target material of higher purity.
