Patent abstract
A capacitor is coupled in parallel with a piezoelectric unit in a sensor. The piezoelectric unit is formed by a film which is sandwiched between a signal electrode and a reference potential electrode. A capacitor is formed by a dielectric film located between the signal electrode and a reference potential electrode. As a result, the capacitance of the sensor element is higher than it would be if the sensor only contained the piezoelectric unit.
