<p>An electronic device with communication capability comprises a metallic housing (122) containing electronic components, and a communication antenna part (90) located in the housing for performing communication with an IC card (110) that incorporates an antenna part (115) and that has a communication capability. When the IC card approaches the housing, the reduction of the inductance of the antenna part of the IC card is suppressed. This is realized by causing a part of the antenna part incorporated in the IC card to be opposed to a part of the communication antenna part and by causing the other part of the antenna part of the IC card to be located in a position so as not to be opposed to the housing (122).</p>
