PROBLEM TO BE SOLVED : To provide a rare earth magnet having high strength and high resistance. SOLUTION : In the rare earth magnet having such a texture as R-Fe-B based rare earth magnet particles 8 are surrounded by a compound layer 2 having high strength and high resistance, the high strength high resistance compound layer 2 consists of a glass principal layer 6 having a texture of glass phase to which R oxide particles are dispersed or not dispersed, and an R oxide particle principal layer 7 formed on the opposite sides of the glass principal layer 6 where an R rich alloy phase 4 containing 50 atom% or more of R exists in the grain boundary of the R oxide particle 3.
