PROBLEM TO BE SOLVED: To provide a magnet which is superior in corrosion resistance than normal, even after a mechanical stress has been applied to it and is formed mostly of corrosible material, and to provide a method of manufacturing the same. SOLUTION: The magnet has hard magnetic particles (K), the hard magnetic particles (K) belonging to the surface layer of the magnet are separated from one another by a first phase (P1), and the other hard particles (K) belonging to the rest of the magnet are separated from one another by a non-magnetic second phase (P2). The first phase (P1) is made to contain, at least an element other than the elements contained in the second phase (P2), the first phase (P1) is set to be more corrosion-resistant than the second phase, and the surface layer is made to have a corrosion-protecting function. |
