PROBLEM TO BE SOLVED : To provide a method of manufacturing a rare earth sintered magnet in which the surface of a sintered body can be efficiently and uniformly coated with a rare earth compound. SOLUTION : The method of manufacturing the rare earth sintered magnet includes : a coating process of coating the sintered body with slurry including the rare earth compound; a rotating process of holding one end in the longitudinal directional of the sintered body and the other end on the opposite side to the one end, and rotating the sintered body on a straight line which is parallel to the longitudinal direction of the sintered body and passes the sintered body, as an axis of rotation; a drying process of coating the sintered body with the slurry and drying the slurry while rotating the sintered body; and a heat treatment process of heat-treating the sintered body having the slurry dried. In the coating process, the slurry is supplied to the sintered body from a direction orthogonal to the axis of rotation while the sintered body is rotated to coat the sintered body with the slurry.
