Abstract
A liquid ejection apparatus includes: channel rows each including individual channels; piezoelectric elements each constituted by an individual electrode, a common electrode, and a piezoelectric layer; and individual wires respectively extending from the individual electrodes to an outside connecting region, connectable to an external circuit board, and each having a contact connectable to an individual terminal of the external circuit board. A portion of each of the channel rows has an intra-row void between adjacent two of the individual channels. Each of the individual wires extends to a portion of the outside connecting region which corresponds to one of the individual channels. A first common wire extending from the common electrode and connectable to a common terminal of the external circuit board is provided at a portion of the outside connecting region which corresponds to the intra-row void.
