  "textContent": "The present invention provides an angular velocity sensor that allows abnormality detection of the sensor from the outside and has further improved in-service reliability. The angular velocity sensor includes a pair of current amplifiers for receiving an output from a sense electrode, a differential amplifier for amplifying output difference between the pair of current amplifiers, a ninety-degree phase shifter constituting a synchronous demodulator for outputting an angular velocity signal by detecting an output from the differential amplifier synchronously with a monitor signal, and a synchronous detector. The monitor signal is added to an input terminal of the current amplifier via a capacitor used as an injector based on an external diagnosis request signal supplied from a control terminal.",
