The present invention relates to a rare-earth magnetic target comprising neodymium, iron, and boron as essential components. The target has an average crystal grain diameter of 10 to 200 µm. It is an object of the present invention to provide a sintered compact target that can form rare-earth magnetic thin films, in particular, neodymium magnetic thin films, having good magnetic characteristics with excellent mass productivity and reproducibility, and provide a method of producing the sintered compact target.
