ABSTRACT:
A liquid jetting apparatus includes: a cavity unit having a plurality of nozzles and pressure chambers; and an actuator unit applying jetting pressures to the pressure chambers. The actuator unit has a plurality of stacked ceramics layers, individual electrodes corresponding to the pressure chambers, a common electrode common to all the pressure chambers, and a barrier layer preventing the liquid from being penetrated therethrough. The barrier layer is stacked on a position which is between a contact surface, of the actuator unit, making contact with the cavity unit and the individual electrodes closest to the contact surface, except a position on the contact surface. It is possible to prevent the individual electrodes and the common electrode from being electrically short-circuited due to the liquid even when the ceramics layer in contact with the cavity unit has a crack.
