Abstract
The present invention provides a thin film magnetic device realizing effective improvement in magnetic permeability in a high frequency area. The thin film magnetic device includes a thin film coil and a plurality of strip-shaped magnetic films disposed along a plane in which the thin film coil extends. The plurality of strip-shaped magnetic films are disposed to extend in one direction only in a pair of areas facing each other. The pair of areas is selected from four areas obtained by dividing, in the winding direction, the area where the thin film coil extends.
