Insulator-Coated Soft Magnetic Powder, Powder Magnetic Core, Magnetic Element, Electronic Device, And Vehicle

摘要

An insulator-coated soft magnetic powder includes a core particle including a base portion containing a soft magnetic material and an oxide film that is provided on a surface of the base portion and that contains an oxide of an element contained in the soft magnetic material, and an insulating particle that is provided on a surface of the core particle and that has an insulating property, wherein an average particle diameter after heat treatment after being subjected to a heat treatment of heating at 1000° C. is 90% or more and 110% or less of an average particle diameter before heat treatment before being subjected to the heat treatment.
