ABSTRACT:
The discharging head for discharging liquid onto a discharge receiving medium includes a vibration plate forming at least a portion of a pressure chamber storing liquid to be discharged and a piezoelectric element, joined to the vibration plate, for generating a pressure forming a discharge force for discharging liquid inside the pressure chamber. A recess is formed in the approximate center of the region of the vibration plate where the piezoelectric element is installed.
