Abstract

See full text

A method of manufacturing a permanent magnet comprises a solution heat treatment. The solution heat treatment includes: performing a heat treatment at a temperature TST; placing a cooling member including a first layer and a second layer on the first layer between the heater and the treatment object so that the first layer faces the treatment object; and transferring the treatment object together with the cooling member to the outside of a heating chamber, and cooling the treatment object until a temperature of the treatment object becomes a temperature lower than a temperature TST−200° C. In the step of cooling the treatment object, a cooling rate until the temperature of the treatment object becomes the temperature TST−200° C. is 5° C./s or more.
