PORTABLE DEVICE AND POWER SUPPLY SYSTEM

摘要

A portable apparatus is provided in which an appropriate magnetic shield can be provided when a shared coil position is used for both low-frequency non-contact power feeding and high-frequency communication. A portable apparatus includes a case, a coil situated towards the exterior of the case, a circuit disposed inside the case to receive power based on a first frequency via the coil and to perform communication based on a second frequency, and a magnetic shield disposed between the coil and an inside of the case, wherein the first frequency is higher than the second frequency, and wherein the magnetic shield has a first portion thereof situated towards the inside, whose permeability is higher at the first frequency than permeability of a second portion situated towards the coil.
