ABSTRACT:
An ink jet head includes: actuators each including a scanning electrode, a piezoelectric element and a recording electrode and arranged in a matrix pattern of n rows by m columns (where n and m are natural numbers equal to or greater than two) in terms of electrical circuit; and a driving circuit for supplying a scanning signal to the scanning electrodes for each column, while supplying a recording signal to each row of the recording electrodes in synchronization with the scanning signal. The actuators are geometrically arranged in n rows by m columns. A relay terminal, extending in a vertical direction, is provided in at least one inter-column space between vertical columns of the actuators for relaying signals from the driving circuit to the recording electrodes and the scanning electrodes. The recording electrodes and the scanning electrodes are connected to the relay terminal via lead wires extending in a horizontal direction.
