Abstract
An electronic timepiece that maintains the mounting integrity of an electronic circuit substrate and an electronic circuit component mounted on the electronic circuit substrate. In a movementincluding a main platecomposed of an electric insulting material, a stepping motor, a wheel train, and a wheel train bridge for supporting the wheel train, an electronic circuit substrate, on which an electronic circuit componentfor controlling the rotation cycle of the stepping motoris mounted, is attached to an end portion of an coil magnetic coreof the stepping motor, and the relatively large electronic circuit componentis positioned by being superimposed on the coil magnetic corein a plane. Accordingly, the electronic circuit substrateformed of a synthetic resin film and the like can be reliably attached to the coil magnetic core, and the mounting integrity the electronic circuit componentcan be maintained.
