| 20080303865 | Ink-jet printer, ink-jet head and method of manufacturing the ink-jet head - A piezoelectric sheet of an ink-jet head includes dummy individual electrodes in addition to individual electrodes which corresponds to respective nozzles.

When the dummy individual electrodes are formed in the non-drive area, a boundary area of the drive area and the non-drive area is uniformly fired when the piezoelectric sheet is manufactured. In the drive area, since surrounding structures of the respective individual electrodes become equal to one another, ink discharge characteristic is substantially uniform in the boundary area of the drive area and the non-drive area. | 12-11-2008 |
