Abstract

A communication terminal includes a close-proximity communication coil, a power transmission coil, and a metal plate. The close-proximity communication coil is configured to be used in a close-proximity communication system. The power transmission coil is configured to be used in a contactless power transmission system. At least a portion of the metal plate is disposed between the close-proximity communication coil and the power transmission coil. The close-proximity communication coil and the power transmission coil are disposed in non-overlapping locations when viewed from a direction perpendicular or substantially perpendicular to a main surface of the metal plate. At least one of the close-proximity communication coil and the power transmission coil electromagnetically couples with the metal plate.
