Abstract: A coated metal powder is a metal powder that contains iron as a main component, and an insulating layer that is formed on a surface of the metal powder and is formed from calcium phosphate and a metal oxide, in which an organosilicon compound is contained on a surface of the insulating layer or inside the insulating layer.

Abstract: A powder magnetic core of the present invention is a powder magnetic core that includes an insulating layer containing a particulate metal oxide between metal powders, in which the insulating layer contains Ca, P, O, Si, and C as elements. According to the present invention, it is possible to provide a powder magnetic core in which securing of a constant permeability characteristic under a high magnetic field and decrease in core loss are compatible with each other, and a method for producing the powder magnetic core.
