Abstract
An electrical connecting structure for a piezoelectric element enables wiring to the piezoelectric element to be carried out without deteriorating the productivity and reliability of the piezoelectric element. The electrical connecting structure is formed by facing a common electrode of the piezoelectric element to a terminal that supplies power to the common electrode and by injecting a conductive adhesive into a through hole, which is formed substantially at the center of the piezoelectric element, from an opening of the through hole that is on the opposite side of the common electrode, thereby securing electrical connection between the terminal and the common electrode of the piezoelectric element.
