A magnetic member is provided to cover a part of the second conductor layer. The second conductor layer is formed such that a side connected to the matching circuit portion from a position where the magnetic member is provided is a radiation portion, and a grounding side from the position where the magnetic member is provided is a non-radiation portion.SELECTED DRAWING: Figure 1
