Abstract
An ink jet recording apparatus comprises actuating portions and lead electrodes for conducting current. The lead electrodes are wired in such a manner that a conductive member is disposed on a surface which is at a side where the ink droplets are ejected and said conductive member is a part of said lead electrode, or one actuating portion is provided with a plurality of lead electrodes, and these lead electrodes are led, substantially in parallel, to terminals which are located at a side opposite to the ejection port with respect to the actuating portion, or one chamber is provided with a plurality of actuating portions which are separated from one another, and lead electrodes connected to the actuating portions are led, substantially in parallel, to terminals which are located at a side opposite to the ejection port with respect to the actuating portion, or the actuating portion is disposed on a conductive member intervened with an insulating layer and the conductive member is a part of the lead electrode.
