摘要
Provided are a method for manufacturing a sintered body for forming a sintered magnet and a method for manufacturing a permanent magnet, which improves the followability to a sintered mold during sintering and prevents cracking of a molded body. Specifically, the compound 12 is produced by pulverizing a magnet raw material into magnet powder, and mixing the pulverized magnet powder and a binder. And the molded object 13 which shape|molded the produced|generated compound 12 is heated up to the calcination temperature by a predetermined|prescribed temperature increase rate in a pressurized state, and it sinters by holding|maintaining at the calcination temperature. In the step of sintering, from the time the temperature rise of the molded object 13 is started to the predetermined timing in the temperature increase of the molded object 13, while making the pressurization value which presses the molded object 13 less than 3 MPa, it is after the timing 3 MPa or more.
