ABSTRACT:
An electronic timepiece with wireless information function that is small, has good reception performance, and has a construction that improves the freedom of design. Antennae5A and5B are disposed inside a short cylindrically-shaped metal case1of which both ends along its cylindrical axis L1are open with the axes L5Aand L5Bof the antennae5A and5B substantially parallel to the cylindrical axis L1of the case1. A magnetic-field-passing part capable of passing the magnetic field of radio waves is disposed in an open side of the case1along an extension of the antenna axis. Radio waves entering from the open side of the case1can therefore be received by the antenna, and the material of the case1does not affect the reception performance of the antennae5A and5B. The case1can therefore be made from metal, increasing the freedom of design and making it possible to improve the appearance.
