More Information
Summary:A piezoelectric device includes an actuator substrate that includes two rows of piezoelectric element rows piezoelectric elements, and a wiring substrate that is disposed so as to face the actuator substrate. The piezoelectric element rows include individual electrodes disposed for each of the piezoelectric elements, and a common electrode common to the piezoelectric elements. The wiring substrate includes a core portion disposed on a surface on the actuator substrate side, an individual wiring portion disposed for each of the piezoelectric element rows that partially covers the core portion, and a common wiring portion disposed for each of the piezoelectric element rows that partially covers the core portion. The two rows of piezoelectric element rows are respectively disposed so as to interpose the core portion. The individual wiring portion and the common wiring portion are respectively electrically connected to the individual electrode and the common electrode.
