Abstract
First and second piezoelectric element overlapped portions of an insulating layer of a flexure part is formed with first and second connecting openings, respectively. There are provided on an upper surface of the insulating layer, first and second lower conductive adhesive agents that electrically connect lower electrode layers of first and second piezoelectric elements to a voltage supply wiring through the first and second connecting openings, and a surrounding insulative adhesive agent that is arranged so as to surround the first and second lower conductive adhesive agents in a plan view.
