A head includes a common ink chamber, a plurality of individual electrodes which communicate with the common ink chamber, and a plurality of ink channels through which, an ink supplied from the common ink chamber flows. Each ink channel is provided with a first electrode which is common for the individual electrodes, a plurality of second electrodes corresponding to the individual electrodes respectively, and an insulating layer which covers the first electrode and the second electrodes. Furthermore, the individual electrode of each ink channel is associated with an individual electrode of another ink channel, and the corresponding second electrodes are in electrical conduction. Accordingly, it is possible to reduce a cost of an electrical system by reducing the number of wirings which are connected to electrodes provided to each of the liquid channels. |
