A ferrite sintered magnet includes a composition expressed by a formula (1) of Ca1-w-xLawAxFezComMnaO19. In the formula (1), “w”, “x”, “z”, “m”, and “a” satisfy a formula (2) of 0.21≤w≤0.62, a formula (3) of 0.02≤x≤0.46, a formula (4) of 7.43≤z≤11.03, a formula (5) of 0.18≤m≤0.41, and a formula (6) of 0.046≤a≤0.188. In the formula (1), “A” is at least one kind of element selected from a group consisting of Sr and Ba.
