The present invention addresses the problem of providing a sintered magnet production method with which the growth of alloy powder particles during sintering can be curbed. Provided is a sintered magnet production method comprising the following: a filling step for filling a cavity of a container with an alloy powder of a stock material for sintered magnets; an orientation step for orienting the alloy powder by applying a magnetic field, without applying mechanical pressure, to the alloy powder with which the cavity has been filled; and a sintering step for sintering the alloy powder, which was oriented in the orientation step, by heating without applying mechanical pressure. The method being characterized in that before the filling step or during the filling step, a powder of a high-melting-point material, for which the median value D50 of the particle size distribution is 0.3 [mu]m or lower and the material of which has a higher melting point than the heating temperature in the sintering step, is mixed into the alloy powder for which the median value D50 is 3 [mu]m or lower as measured by laser diffraction.
