摘要： An ink jet head includes a pressure chamber formed to hold ink, a vibrating plate, a driving element, and a protective film covering the driving element. The vibrating plate is provided at one end of the pressure chamber, and has a first opening through which the ink held in the pressure chamber is discharged. The driving element is provided on a surface of the vibrating plate and is configured to cause a volume of the pressure chamber to be changed by deforming the vibrating plate upon application of voltage to the driving element. The protective film has a second opening aligned with the first opening and through which the ink held in the pressure chamber is discharged.
