Abstract
A piezoelectric element prevents the development of a short circuit between separate electrodes and provides a high level of connection reliability. The piezoelectric element utilizing a longitudinal oscillation mode includes a piezoelectric substrate which has on one main surface thereof a first electrode and a second electrode separated by longitudinally extending linear grooves and, on the other main surface, a third electrode. Conductive support members are secured to node sections of the first and second electrodes so as to be spaced apart from each other with respect to the longitudinal dimension of the piezoelectric substrate.
