Abstract:
According to one embodiment, an inkjet head includes actuators configured to pressurize ink. The actuators include piezoelectric elements provided on an insulating layer, first electrodes electrically connected to the piezoelectric elements, and second electrodes connected to the piezoelectric elements and configured to hold the piezoelectric elements in cooperation with the first electrodes. The first electrodes of all the actuators are electrically connected to a common first energization pattern. The second electrodes of all the actuators are individually electrically connected to second energization patterns. The first energization pattern and the second energization patterns are separated from each other without overlapping each other on the insulating layer.
