Abstract
A plurality of inductors are formed by connecting linear patterns formed in different surfaces of a substrate respectively by means of holes, forming a plurality of electrically neutral surfaces in areas not including the linear patterns on different surfaces of the substrate, and furthermore by forming electrically neutral holes connecting the electrically neutral surfaces to each other at positions between the plurality of inductors to affect the coupling between inductors.
