PROBLEM TO BE SOLVED: To obtain a vibration gyro which can be produced easily at a low cost, eliminate any influence due to the changes in atmospheric temperature or external impact and has a high detection sensitivity for rotational angular velocity. SOLUTION: A vibration gyro 10 includes a vibrating body 12 for driving where both ends of two vibration pieces 14a and 14b are connected with each other. The body 16 is arranged in a manner to cross the body 12 at right angles between the pieces 14a and 14b by means of connecting elements 18. Piezoelectric elements 20a and 20b are formed on the pieces 14a and 14b. Piezoelectric elements 28a and 28b for detection are formed on both sides of the element 18 in one surfacial direction of the body 16. |
