Abstract

See full text

A first coil element includes a first loop-shaped conductor and a second loop-shaped conductor. A second coil element includes a third loop-shaped conductor and a fourth loop-shaped conductor. The first loop-shaped conductor and the second loop-shaped conductor are sandwiched in a stacking direction between the third loop-shaped conductor and the fourth loop-shaped conductor. A conductive pattern which is a portion of the first loop-shaped conductor and a conductive pattern which is a portion of the second loop-shaped conductor are connected in parallel. Then, each of a conductive pattern which is a remaining portion of the first loop-shaped conductor and a conductive pattern which is a remaining portion of the second loop-shaped conductor is connected in series with the parallel circuit.
