Abstract
A tuning fork vibrator includes a vibrating body having the shape of a tuning fork as a whole. The vibrating body includes legs having a meandering shape and a base coupled to an end of the legs. A support is formed so as to extend between the legs from the base. Two electrodes arranged separately in the width direction are formed on one of the legs, and two electrodes arranged separately in the width direction are formed on the other of the legs. The outermost electrodes on each of the legs are connected to a connection electrode formed on the base. The connection electrode is formed so as to extend toward the support. The innermost electrodes on each of the legs are formed so as to extend toward the support through the base. A common electrode is formed on a second principal surface of the vibrating body. A vibratory gyroscope can be formed using the tuning fork vibrator.
