Abstract
A sixth coil electrode forming a first coil is electrically connected to a twelfth coil electrode forming a second coil, for example, via a second capacitor electrode in a second capacitor electrode layer. Thus, an induction body has a permeability significantly smaller than the permeability of a magnetic body (for example permeability μ=1). Accordingly, it is possible to minimize the permeability to such a degree that it is possible to ignore the connection between the first coil and the second coil appearing equivalently and to obtain a desired frequency characteristic.
