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 by mixing the pulverized magnet powder and the binder compound (12). Then, the fabricated green sheet 14 is molded to produce a compound (12) in a sheet form. Thereafter, it was a magnetic field orientation of the molded green sheet 14, and also carries out a green sheet 14, the number of preliminary firing process by holding time under a non-oxidizing atmosphere pressure at a pressure greater than atmospheric pressure at 200 ℃ to 900 ℃. Subsequently, to prepare a permanent magnet (1) by sintering a green sheet (14) at the firing temperature.
