Zusammenfassung:A powder magnetic core capable of achieving a low loss in a high frequency range is provided. A powder magnetic core according to the present disclosure is a powder magnetic core in which a magnetic powder is bonded via a binder layer. A volume filling percentage of the magnetic powder included in the powder magnetic core is 85 volume % or higher, and a value obtained by dividing a BET specific surface area (m2/g) of the powder magnetic core by a specific surface area (m2/g) calculated using outer dimensions of the powder magnetic core is 5000 or less.
