摘要：
In a method for manufacturing a powder magnetic core, magnetic layer green sheets is formed by using magnetic metal particles-having an insulating oxide layer on a surface thereof, and insulating layer green sheets are formed by using insulating particles. The magnetic layer green sheet and the insulating layer green sheet are alternately laminated, and the layers are press molded.
