Abstract
In a head, a passageway member has a nozzle which is opened in a first major surface, and a pressurizing chamber which is communicated with the nozzle and is positioned on a second major surface side as the back face of the first major surface. A piezoelectric actuator substrate is superimposed on the second major surface and covers over the pressurizing chamber. An FPChas an insulating base film, an interconnect which is provided on one major surface of the base film, and an insulating film covering the interconnect, and makes its insulating film side face to the side of the piezoelectric actuator substrate which is opposite to the passageway member side. Above the pressurizing chambers, a thickness T of the insulating film from the base film is different between one side and the other side in a predetermined direction along the second major surface.
