Abstract:
1. An electronic timepiece with a contactless data communication function comprising: a contactless communication unit for contactless data communication with an external transceiver device: a conductive member formed effectively into a semi-ring; an insulative member attached along the circumferential direction of said conductive member to complete a ring shape with said conductive member; a time measuring means; and a time information display unit; wherein the contactless communication unit includes an antenna for producing a magnetic field in the circumferential axis direction of the conductive member, and a transceiver means for contactless data communication via the antenna; the conductive member is part of a case housing the time measuring means; and the insulative member constitutes a conductive gap electrically isolating ends of the conductive member in the circumferential direction thereof, and includes a non-conductive member disposed inside this gap.
