PURPOSE:To provide a shock-resistant rare-earth cobalt magnet, whose shock resistance and mechanical strength are improved without reducing its magnetic characteristics, and a method of manufacturing the cobalt magnet. CONSTITUTION:A single-layer metal-plated layer 2 having a thickness, which exceeds 2mum and is 7mum or thinner, is formed on the surface of a magnet main body 1 consisting of a rare-earth cobalt sintered material, which is shown by the composition formula=R1Co5 or R2Co17 (where R is at least one of a metal of rare-earth metals of Sm, Pr, La, etc.). |
