Provided are a rare earth permanent magnet in which the magnetic performance has been improved by improving the millability in a wet-milling process, and a production method for a rare earth permanent magnet. A coarsely-milled magnet powder and an organometallic compound represented by the general formula M-(OR)x (where M includes at least one element from Nd, Al, Cu, Ag, Dy, Tb, V, Mo, Zr, Ta, Ti, W, and Nb; R is a substituent comprising a hydrocarbon of a carbon chain length of 2-16, either straight chain or branched; and x is any integer) are wet-milled in an organic solvent, thereby milling the magnet starting material into a magnet powder, as well as causing the organometallic compound to become deposited on the particle surfaces of the magnet powder. The magnet powder on which the organometallic compound has been deposited is then molded and sintered to produce a permanent magnet (1). |
