ABSTRACT:
A vibrating gyro which includes a vibrator formed by joining two piezoelectric substrates, which are polarized in opposite directions, by a metal layer. Electrodes are formed on the main outer surfaces of the piezoelectric substrates. One of the electrode is split into six electrode portions. As the metal layer, a material having a melting point lower than the Curie point of the piezoelectric substrates is used. Cut portions are formed on the joining sides of the piezoelectric substrates, and high-temperature metal wires or the like are passed through the cut portions, thereby forming support members.
