摘要：
An insulator-coated soft magnetic powder contains: a soft magnetic powder; and an insulating film with which a particle surface of the soft magnetic powder is coated and which contains a fluorine compound, in which an average particle diameter of the soft magnetic powder is 1 μm or more and 15 μm or less, an average thickness of the insulating film is 5 nm or more and 50 nm or less, and a relative permittivity of the fluorine compound is 5.0 or less.
