DROPLET EJECTING APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

Provided is an efficient droplet ejecting apparatus, which has high assembly accuracy even with a simple structure and simple assembly steps and transmits expansion and contraction of a piezoelectric element to a protruding section. A method for manufacturing such droplet ejecting apparatus is also provided. The droplet ejecting apparatus is provided with a pressurizing chamber communicating with a nozzle (41); a vibrating membrane forming a part of the pressurizing chamber; a piezoelectric element (10) for vibrating the vibrating membrane; a protruding section provided on the vibrating membrane by being connected to the piezoelectric element (10), for transmitting vibration to the vibrating membrane; and a bracket (20). The droplet ejecting apparatus ejects a droplet from the nozzle (41). A member provided with the pressurizing chamber, the vibrating membrane and the protruding section can be fixed to the bracket (20). The bracket (20) is provided with a groove section between a releasing section and the protruding section, for guiding the bar-shaped piezoelectric element (10). The piezoelectric element (10) is adhered in the groove section.
