PROBLEM TO BE SOLVED : To effectively suppress the deformation of sintered compacts by uniformizing heating temperature in a sintering vessel.
SOLUTION : Regarding the method for producing rare earth sintered magnets where sintering is performed in a state where a plurality of molded bodies G composed of alloy powder having a prescribed composition are arranged within a sintering vessel 10, the sintering vessel 10 is composed of : an outside vessel 11; and an inside vessel 12 arranged at the inside of the outside vessel 11 and storing the molded bodies G, a first thermal shielding body 13 is arranged between the outside vessel 11 and the inside vessel 12, and also, a second thermal shielding body 14 surrounding the outer circumferences of the plurality of molding bodies G is arranged within the inside vessel 12.
