ABSTRACT:
The ink-jet printer head includes a cavity unit which has a plurality of pressure chambers arranged in a plurality of pressure-chamber rows; an actuator unit which has individual surface electrodes corresponding to the pressure chambers respectively, and land portions conducted to the individual surface electrodes respectively; and a flexible cable which has connection terminals and signal lines. The land portions and the connection terminals are electrically connected. In each of the pressure-chamber rows, the land portions are arranged such that a certain land portion is shifted from another land portion adjacent to the certain land portion in a longitudinal direction of the pressure chambers. Accordingly, even when the pressure chambers are arranged highly densely, it is possible to electrically connect the flexible cable and the actuator unit easily.
