摘要 |
An ink-jet head has an actuator comprising conductive layers and piezoelectric ceramic layers which are alternately formed layer by layer in a cylindrical form so as to provide a hollow portion at the actuator center. The hollow portion corresponds to an ink chamber out of which ink is jetted. A process for manufacturing the ink-jet head is also disclosed.
