Abstract
A magnetic material which is likely to be cracked or chipped. The magnetic material is a magnetic material including ferrite particles and segregated particles containing Bi and Si, and characteristically, the magnetic material contains, as a main constituent, 46.0 mol % to 50.0 mol % FeO, 0.4 mol % to 8.0 mol % CuO, 23.0 mol % to 32.0 mol % ZnO, and 18.0 mol % to 22.0 mol % NiO, and the ratio of the average particle size of the segregated particles to the average particle size of the ferrite particles is 0.04 or more and 0.19 or less (i.e., 0.04 to 0.19).
