Abstract:
A planar-type wireless power-receiving circuit module includes a planar ground conductor, a substrate, a power-receiving coil, and a magnetic sheet. The planar ground conductor has a cavity in the middle section thereof. The substrate is disposed on a first main surface of the planar ground conductor. The substrate includes dielectric layers stacked on top of each other in a manner so as to form electronic circuitry. The power-receiving coil is electrically connected to the electronic circuitry and is disposed in the cavity. The magnetic sheet overlaps the power-receiving coil when the planar ground conductor is viewed in plan. The magnetic sheet is part of a path of magnetic flux passing through the power-receiving coil and is disposed on a first main surface of the power-receiving coil.
