To prevent the deterioration of magnetic characteristics provides a method for producing a rare earth permanent magnet, and possibly rare earth permanent magnet. Pulverizing the magnet raw material with the magnetic powder, and produces a mixture made by mixing a binder, including polymer or copolymer or a mixture thereof that does not contain the pulverized magnet powder, the long chain hydrocarbon group or an oxygen atom monomer. And, by molding the resultant mixture in a sheet form to prepare a green sheet. Then, by raising the temperature to remove the binder was removed by decomposition to scattering of the monomer, and by a binder by keeping a certain amount of time for the fabricated green sheet as a binder, a decomposition temperature in a non-oxidizing atmosphere such as depolymerization green sheet in the firing temperature for sintering It is adapted to prepare a permanent magnet (1) by line.
