Electronic timepiece with stable IC mounting

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 movement 1 including a main plate 2 composed of an electric insulting material, a stepping motor 10, a wheel train 4, and a wheel train bridge for supporting the wheel train 4, an electronic circuit substrate 20, on which an electronic circuit component 22 for controlling the rotation cycle of the stepping motor 10 is mounted, is attached to an end portion of an coil magnetic core 12 of the stepping motor 10, and the relatively large electronic circuit component 22 is positioned by being superimposed on the coil magnetic core 12 in a plane. Accordingly, the electronic circuit substrate 20 formed of a synthetic resin film and the like can be reliably attached to the coil magnetic core 12, and the mounting integrity the electronic circuit component 22 can be maintained.
