A vibrating gyroscope 10 comprises a tubular member 12 made of a piezoelectric material. The tubular member 12 is polarized in its thickness direction. A common electrode 14 is formed on the inner surface of the tubular member 12, and outer electrodes 16a, 16b, 16c are formed on the outer surface of the tubular member 12. The outer electrodes 16a, 16b, 16c are spaced in the circumferential direction of the tubular member 12. A vibrating member 18 passes through the inside of the tubular member 12.
