Abstract
A method of manufacturing an ink-jet head includes preparing a sheet-like piezoelectric material comprising an internal electrode and forming a plurality of individual electrodes at equal intervals in a drive area and an area around the drive area on a surface of the sheet-like piezoelectric material. The method also includes forming a piezoelectric sheet which comprises the plurality of individual electrodes and the internal electrode opposite to the respective individual electrodes by firing the piezoelectric material in which the individual electrodes are formed and forming a plurality of individual electrodes for drive voltage application on a board which drives the piezoelectric sheet. The method further includes electrically connecting the respective individual electrodes in the drive area of the piezoelectric sheet to the respective individual electrodes formed on the board.
