An electronic timepiece with wireless information function that is small, has good reception performance, and has a construction that improves the freedom of design. Antennae 5A and 5B are disposed inside a short cylindrically-shaped metal case 1 of which both ends along its cylindrical axis 'L1 are open with the axes L5A and L5B of the antennae 5A and 5B substantially parallel to the cylindrical axis LI of the case 1. A magnetic-field-passing part capable of passing the magnetic field of radio waves is disposed in an open side of the case 1 along an extension of the antenna axis. Radio waves entering from the open side of the case 1 can therefore be received by the antenna, and the material of the case 1 does not affect the reception performance of the antennae 5A and 5B. The case 1 can therefore be made from metal, increasing the freedom of design and making it possible to improve the appearance.
