Abstract
Official abstract text for this publication.
An ink jet head includes a substrate including a mounting surface and a pressure chamber open to the mounting surface. The ink jet head further includes a nozzle plate including an inner surface fixed to the mounting surface and covering the pressure chamber, a nozzle open to the pressure chamber, and a piezoelectric element surrounding the nozzle and configured to deform to thereby change a volume of the pressure chamber. The ink jet head further includes a deformation control unit disposed on and extending from the inner surface of the nozzle plate and surrounding the nozzle, the deformation control unit configured to cause deformation of the piezoelectric element to be substantially symmetric with respect to the nozzle.
