PROBLEM TO BE SOLVED: To provide a production method for realizing a target material having high density and a uniform structure by using a discharge plasma sintering method as a sintering method having excellent production efficiency among powder metallurgical methods. SOLUTION: In the method for producing a target material, raw material metal powder is introduced into thermal plasma, thus spheroidal metal powder subjected to spheroidizing is packed into a die, and the spheroidal metal power is sintered at a direct current pulse current density of≥5 A/mm<SP>2</SP>under a pressure of≥20 MPa in a pressure-reduced atmosphere of≤200 Pa.
