Abstract

PURPOSE: To make it possible to improve the temperature characteristic of frequency of the vibrator, by providing driving electrodes used for bar shaped piezo-electric vibrator on the top and reverse sides of the vibrator, and fixing one end of the vibrator and keeping the other end freely, so that a small and highly accurate piezo-electric vibrator which is suitable to give piezo-electric vibrations to watches, can be obtained.
