PROBLEM TO BE SOLVED : To provide an inexpensive ferrite magnet exhibiting excellent magnet characteristics even in a compositional region of the stoichiometric composition and a compositional region of slightly excessive SrO as compared with the stoichiometric composition. SOLUTION : The ferrite magnet is composed of a single phase of magnetoplumbite represented by a formula (Sr1-xAx)O-n[(Fe3+1-yFe2+y)2O3], where A is at least one kind being selected from rare earth elements, x, y and n represent mol ratios in the ranges of 0
