    To provide a ferrite sintered magnet which has a further increased Br while retaining a high Hcj.SOLUTION: A ferrite sintered magnet comprises ferrite particles having a hexagonal structure. In a cross section in parallel with an easily magnetizable axis, an average value W of circularities of the ferrite particles satisfies 0.56≤W≤0.68.SELECTED DRAWING: Figure 1A

    【課題】高いＨｃｊを維持したままＢｒをさらに向上させたフェライト焼結磁石を得る。【解決手段】 六方晶構造を有するフェライト粒子を含むフェライト焼結磁石である。磁化容易軸に平行な断面において、フェライト粒子の円形度の平均値をＷとして、０．５６≦Ｗ≦０．６８を満たす。【選択図】図１Ａ
