A neodymium-based rare-earth permanent magnet characterized in that the purity of the magnet excluding any gas components and any component elements is 99.9 wt% or higher. The present invention addresses the problem of providing a high-performance neodymium-based rare-earth permanent magnet. By highly purifying the magnetic materials, the neodymium-based rare-earth permanent magnet can be made to have extremely improved magnetic properties and, furthermore, the heat resistance and corrosion resistance, which are inherent drawbacks of magnetic materials, have been improved.
