Abstract: A powder magnetic core having excellent specific resistance or strength. The powder magnetic core has soft magnetic particles, first coating layers that coat the surfaces of the soft magnetic particles and include aluminum nitride, and second coating layers that coat at least a part of the surfaces of the first coating layers and include a low-melting-point glass having a softening point lower than an annealing temperature for the soft magnetic particles.

The powder magnetic core can stably exhibit a higher specific resistance and higher strength than the prior art owing to such a synergistic action of the first coating layers and second coating layers.
