<p>An electronic clock (100) having a non-contact data communication function. A case body (101) of the electronic clock is formed of a conductive material such a metal, and formed in an annular shape having a front-side opening part (101A) and a back-side opening part (101B). A space (101G) is provided in the case body (101) as an insulation part on a part of the circumferential direction, and an insulating material (109) is disposed in and fixed to the space (101G). Since generation of eddycurrent can be prevented, degradation of the communication function can be suppressed even when an annular conductive member is used for the case body and other components. In addition, the strength of the case body can be improved, and sealability or waterproofness can be easily ensured, and thus, the reliability of the electronic clock can be heightened.</p> |
