摘要:
According to one embodiment, an ink-jet head includes a piezoelectric member which forms an ink pressure chamber, an electrode disposed on a side surface of the piezoelectric member, a nozzle plate attached to the piezoelectric member and including a nozzle hole communicating with the ink pressure chamber, a surface of the nozzle plate including a top surface of the nozzle plate, and a protection film which covers the surface of the nozzle plate, a peripheral portion of an adhesion part between the piezoelectric member and the nozzle plate, and the electrode. A recess is formed in a part of the protection film covering the top surface of the nozzle plate. The part of the protection film corresponds to a peripheral area of the nozzle hole.
