PROBLEM TO BE SOLVED : To provide a method by which a rare-earth element permanent magnet, that is superior in both coercive force and residual magnetic flux density can be manufactured. SOLUTION : After a mixture of alloy X powder, composed mainly of R 2 T14 B (where R , T, and B respectively denote one or more kinds of rare earth elements including Y (Dy is indispensable), one or more kinds of transition metal elements, and boron) and alloy Y powder, composed mainly of R T (where R and T respectively denote one or more kinds of heavy rare-earth elements and one or more kinds of transition metal elements) is obtained, the mixed powder is sintered. The magnetic characteristics of the rare-earth permanent magnet can be improved, by adjusting the Dy ratio which is the ratio of the content of the heavy rare-earth elements in the alloy X powder to that of the heavy rare-earth elements in the sintered magnet composition to be 0.38-0.99 and R ratio, which is the ratio of the content of the rare-earth elements in the alloy X powder to that of the rare-earth elements, in the sintered magnet composition to be 0.94-1.03.
