COMMUNICATION TERMINAL DEVICE, POWER SUPPLY METHOD, AND POWER SUPPLY PROGRAM

摘要

A communication terminal device including a non-contact IC card having an IC and an antenna module. The IC is mounted on a control substrate of the communication terminal device and the antenna module is mounted on a battery cover or a battery. The device further includes an electric connection path for electrically connecting the IC to the antenna module, an electro-magnetic cutoff sheet mounted between the antenna module and the control substrate, and an electric insulation sheet mounted between the antenna module and the electro-magnetic cutoff sheet.
