Anisotropic rare earth sintered magnet and method for producing same

Provided are: an anisotropic rare earth sintered magnet which contains Ce and has a compound of an Nd2Fe14B-type crystal as a main phase, and which exhibits good magnetic characteristics; and a method for producing the anisotropic rare earth sintered magnet. The anisotropic rare earth sintered magnet according to the present invention has a composition represented by formula Rx (Fe1-aCoa) 100-x-y-zByMz (wherein R represents two or more elements selected from the group consisting of rare earth elements and must contain Nd and Ce), and is characterized in that the main phase is composed of a compound of an Nd2Fe14B-type crystal, and the main phase is composed of a compound of an Nd2Fe14B-type crystal. A main phase crystal grain (10) having a Ce/R'ratio (R 'is one or more elements selected from rare earth elements and containing Nd as necessary) in a crystal grain center portion lower than the Ce/R' ratio in a crystal grain shell portion is present, and an R '-rich phase containing Ce and an R' (Fe, Co) 2 phase
