主权项 1. A method for producing a permanent magnet for a motor, to be buried in a permanent magnet motor, comprising: a step of pulverizing a magnet raw material in an organic solvent, a step of mixing the magnet raw material and a resin binder in the organic solvent to produce a magnet powder, a step of molding the slurry into a sheet form to prepare green sheets of the magnet powder, a step of applying a magnetic field to the green sheets thereby orienting the magnetic field, and a step of alternately laminating the green sheets of the magnet powder and an insulating layer and sintering the laminated plural layers, wherein the permanent magnet is a Nd-based magnet.
