Abstract
A battery electrode terminal member has a spring plate structure comprised of a base body part configured to be mounted to and supported by a casing of a timepiece main body in substantial perpendicular relation to a main face of the timepiece main body. A battery electrode contact terminal part of the spring plate structure extends from one end of the base body part for elastical pressure contact with a peripheral face part of an electrode of a battery.

An electronic timepiece, comprising:
- a timepiece main body having a main face;
- a battery electrode terminal member having a spring plate structure made of a plurality of parts and mounted to and supported by the timepiece main body so that a normal line extending from a main face of each of the plurality of parts is parallel to the main face of the timepiece main body, the plurality of parts comprising a base body part and a battery electrode contact terminal part extending from one end of the base body part for elastical pressure contact with a peripheral face part of an electrode of a battery;
- and an oscillator having a case body;
- wherein the plurality of parts further comprises an oscillator case body part extending from an end of the base body part opposite to the end thereof from which the battery electrode contact terminal part extends, the oscillator case body part being disposed in elastical pressure contact with the case body of the oscillator.
