An alloy material for an R-T-B-based rare earth permanent magnet, including (i) an R-T-B-based alloy composed of R being two or more members selected from rare earth elements, T being a transition metal that essentially contains Fe, B and unavoidable impurities, and in which the Dy content is more than 10% by mass and less than 31% by mass, and (ii) a metal powder. Also disclosed is a method for producing an R-T-B-based rare earth permanent magnet and a motor provided with the R-T-B-based rare earth permanent magnet.
