Provided is a production method and a production device for producing each of the rare earth sintered magnet sintered bodies without carrying a mold in a sintering furnace. The production method comprises a powder feeding step of feeding an alloy powder into a mold having side walls divided into two or more sections; a filling step of filling the alloy powder into the mold to prepare a filled molded-body; an orienting step of orienting the alloy powder in the filled molded-body by applying a magnetic field to the filled molded-body to prepare an oriented filled-molded-body; a retrieving step of detaching the side walls of the mold from the oriented filled-molded-body and retrieving the oriented filled-molded-body from the mold; and a sintering step of sintering the retrieved oriented filled-molded-body, wherein the filling step and the orienting step are performed at different locations, and it is preferred that a pulsed magnetic field is applied in the orienting step and inside of the mold is partitioned into a plurality of cavities by partitions.
