    • It is an object of the invention to increase the drive efficiency of an angular speed sensor, which uses s tuning fork of a single-crystal piezoelectric material such as quartz. An angular speed sensor comprises driving electrodes (1, 2) and detection electrodes (3, 4) provided, respectively, on first and second main surfaces, the outside surface and the inside surface of one prong (10a) of a tuning fork (10); and a driving electrode (5), a monitor electrode (6), and detection electrodes (7, 8) provided, respectively, on first and second main surfaces, the inside surface and the outside surface of the other prong (10b). A power supply (9) applies drive voltage so that the driving electrodes (2,5) may have the same polarity and that the driving electrode (1) may have the opposite polarity to the driving electrodes (2,5).

    • A failure of an angular velocity sensor is detected when a sensing electrode or a circuit in the sensor fails. An angular velocity sensor comprises an element unit composed of a first exciting section (2a, 2b) for imparting drive vibration to a vibrator (1), a vibration sensing section (3) for measuring the vibration level of the vibrator (1), and a Coliolis sensing section (4a, 4b) for sensing the Coliolis vibration in response to the input angular velocity and a circuit unit (8) composed of a drive circuit (9) that receives the signal from a vibration sensing section (3) and outputs a signal to the first exciting section (2a, 2b) and a sensing circuit that receives the signal from the Coliolis sensing section (4a, 4b). The circuit unit (8) is further composed of a fail detecting section (11) that includes a level discriminating circuit (11b) for discriminating an abnormal level of the charge of the Coliolis sensing section and that serves as output means for outputting a signal upon detecting an abnormality. The Coliolis sensing section (4a, 4b) has electrodes so arranged and adjusted that the two electrodes output signals each including a drive vibration component of a level equal to or higher than a reference level of the level discriminating circuit (11b) and that the level of a signal generated by combining the two signals is equal to or lower than the reference level.
