摘要：
A sintered ferrite magnet having an M-type ferrite structure and comprising Ca, an R element which is at least one rare earth element indispensably including La, Ba, Fe and Co as indispensable elements, which is represented by Ca 1-x-y R x Ba y Fe 2n-z Co z , wherein (1-x-y), x, y, z and n are numbers representing the amounts of Ca, the R element, Ba and Co and a molar ratio, meeting 0.2 ≤ x ≤ 0.65, 0.001 ≤ y ≤ 0.2, 0.03 ≤ z ≤ 0.65, and 4 ≤ n ≤ 7.
