Insulator-coated soft magnetic powder, method for producing insulator-coated soft magnetic powder, powder magnetic core, magnetic element, electronic device, and vehicle

An insulator-coated soft magnetic powder, comprising:

• core particles each of which includes a base portion containing a soft magnetic material and an oxide film provided on the surface of the base portion and containing an oxide of an element contained in the soft magnetic material;
• ceramic particles which are provided on the surface of each of the core particles and have an insulating property;
• and
• a glass layer that encapsulates the surface of each of the core particles, has an insulating property, and contains at least one type of phosphorus oxide, bismuth oxide, zinc oxide, boron oxide, tellurium oxide, and silicon oxide as a main component, wherein
• the ceramic particles are dispersed throughout the glass layer that encapsulates the surface of each of the core particles, the ceramic particles are included in a proportion of 100 vol % or more and 500 vol % or less of the glass layer, and have an average particle diameter that is 1 nm or more and 500 nm or less,
• a thickness of the glass layer that encapsulates the surface of the core particles is greater than the average particle diameter of the ceramic particles, and
• wherein the ceramic particles contain aluminum oxide or zirconium oxide.
