RARE-EARTH SINTERED MAGNET

[Problem] The purpose of the present invention is to provide a rare-earth sintered magnet having good magnetic properties. [Solution] This rare-earth sintered magnet contains main phase crystal grains having an Nd5Fe17-type crystal structure, comprises R and T (where R represents one or more rare-earth elements that essentially include Sm, and T represents Fe or one or more transition metal elements that essentially include Fe and Co), and is characterized in that : the compositional ratio of R in the rare-earth sintered magnet is 20-40 at% and the remaining portion is substantially T; the remaining portion other than R in the rare-earth sintered magnet is substantially only T or only T and C; and when the average grain size of the main phase crystal grains in one cross-sectional surface of the rare-earth sintered magnet is defined as Dv, while the grain size of individual main phase crystal grains is defined as Di, Dv is at least 1.0 μm, and the area ratio of main phase crystal grains that satisfy 0.7Dv≤Di≤2.0Dv is at least 80% with respect to the area of a cross-sectional surface of the rare-earth sintered magnet.
