Abstract
An angular velocity sensor includes a vibrator that vibrates with a drive signal; and a first-sensing-electrode on the vibrator that outputs a first signal containing a first-sense-component generated based on an angular velocity of the vibrator and a first-monitor-component generated based on a drive signal. The sensor includes a second-sensing-electrode on the vibrator that outputs a second signal containing a second-sense-component with a phase substantially the same as that of the first-sense-component and a second-monitor-component with a phase substantially opposite to that of the first-monitor-component; a first-signal-line one end of which is connected to the first-sensing-electrode; and a second-signal-line one end of which is connected to the second-sensing-electrode. The sensor includes a first-sensing-terminal connected to the other ends of the first- and second-signal-lines; and a disconnection-sensing-circuit that outputs a disconnection-sense-signal indicating that the first- or second-signal-line is disconnected, based on a signal from the first-sensing-terminal.
