Abstract
The pattern line width of a coil is partially widened in a predetermined dimension and wiring patterns of a coil on the surface side and a coil on the rear side are arranged so as not to be in overlapped positions. Consequently, a direct current resistance of the coil can be reduced and an adverse influence by a self resonance of the coil on a communication can be reduced.
