Document Type and Number:
Japanese Patent JP6266725
Kind Code:
B2
Abstract:
According to an embodiment, an inkjet head includes a nozzle from which ink is ejected, an ink pressure chamber, an oscillating plate, a first electrode, a piezoelectric layer, a second electrode, and a passivation layer. The ink pressure chamber is provided in the inkjet head to supply ink to the nozzle. The oscillating plate is formed to surround the nozzle. The first electrode is formed to surround the nozzle and to be in contact with the first oscillating plate. The piezoelectric layer is configured to surround the nozzle and to be in contact with the first electrode. The second electrode is formed to surround the nozzle and to be in contact with the piezoelectric layer. The passivation layer is formed to surround the nozzle and to be in contact with the first electrode, the second electrode, or the first oscillating plate.
