ELECTRONIC DEVICE HAVING METAL PACKAGE UNIT HAVING BUILT-IN ANTENNA UNIT

摘要

There is provided an electronic device having a metal package unit having a built-in antenna unit having a preferable radio wave reception performance and not restricted by the material or the design. The electronic device (30) includes at least an antenna unit (32), an information processing device (33) for processing information acquired by the antenna unit (32), and a metal package unit (31) for containing the antenna unit (32) and the information processing device (33) inside. The metal package unit (31) is configured in such a manner that the antenna unit (32) receives a magnetic flux via the metal package unit (31) from outside of the metal package unit (31) so that it can be resonated and the metal package unit (31) has at least a part having an electric resistance value different from the electric resistance value of the other part of the metal package unit (31).
