Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sintered magnet that satisfies reduction of rare earth elements that are rare resources and increase of coercive force and a maximum energy product.SOLUTION: An Fe-based powder of high saturation magnetic flux density is mixed with a NdFeB-based magnetic powder. The Fe-based powder has shape anisotropy and a surface of which is coated with a fluoride containing heavy rare earth element by a solution treatment. An average particle diameter of the Fe-based powder is larger than an average particle diameter of the NdFeB-based magnetic powder.
