Abstract
A piezoelectric deflection sensor includes a first piezoelectric plate having a polarization axis direction that is parallel to first and second principal surfaces, first and second segmented electrodes provided on the first principal surface of the first piezoelectric plate, and third and fourth segmented electrodes provided on the second principal surface of the first piezoelectric plate. A piezoelectric element is defined by the first piezoelectric plate and the first to fourth segmented electrodes. The first segmented electrode and the third segmented electrode oppose each other across the first piezoelectric plate, and the second segmented electrode and the fourth segmented electrode oppose each other across the first piezoelectric plate. The first segmented electrode and the fourth segmented electrode are electrically connected to each other, and the second segmented electrode and the third segmented electrode are electrically connected to each other.
