To provide an inductor which can be improved in insulation properties while being suppressed with a decline in inductance.
Such an inductor is assumed, wherein a coil is embedded in a core consisting of a press-formed body of a ferromagnetic metal powder where the surface of ferromagnetic metal particles 6 is coated with an insulating material having a hardenability. The insulation layer which coats the surface of the ferromagnetic metal particles 6 consists of a plurality of insulation films 5a-5c, each formed of an insulating material hardened individually. By forming the insulation film from the insulation films 5a-5c hardened individually, a strong insulation film 5 can be obtained, and hence the insulation properties can be improved and a decline can be suppressed in inductance.
