Liquid jetting head and method for manufacturing the same
A liquid jetting head includes a flow channel substrate formed with pressure chambers, an actuator covering the pressure chambers, and a temperature sensor. A dummy pressure chamber is formed in a surface, of the flow channel substrate, in which the pressure chambers are open. The actuator includes: a vibration plate which covers the pressure chambers and the dummy pressure chamber and which has a first surface facing the pressure chambers and a second surface opposite to the first surface, and a piezoelectric body arranged on the second surface of the vibration plate to face the pressure chambers. The temperature sensor is arranged on the second surface of the vibration plate at a position facing the dummy pressure chamber.
