A composite magnetic body comprising a flaky metal soft magnetic powder in a volume content of 35% or more and 55% or less, wherein the phosphazene compound, the binder resin, and the phosphorus-free flame-retardant additive (1) Wherein the composite magnetic body further comprises: 0.17? P / B? 0.21 (1) 0.89? (PN + RA) / B? 2.71 (2) (Wherein, PN represents the mass% of the phosphazene compound in the composite magnetic body, RA represents the mass% of the flame-retardant auxiliary in the composite magnetic body, B represents the mass% of the binder resin in the composite magnetic body, Mass%). The composite magnetic material can impart high flame retardancy without performance loss such as permeability. |
