Multilayered magnetic film having buffer layer inserted between resin layer and laminated magnetic film layer and thin film inductor using the same

摘要

A multilayered magnetic film comprises a resin layer and multilayered magnetic film layer including one or more than one magnetic layers and one or more than one insulation layers and separated from the resin layer by a predetermined distance. A buffer layer is inserted into at least part of the interface between the resin layer and the multilayered magnetic film layer. The magnetic layer or layers of the multilayered magnetic film layer contain at least Fe and Co or at least Fe, Co, B and C.
