Abstract
An inkjet recording head includes a plurality of nozzles, a plurality of pressure chambers in communication with the respective nozzles, a diaphragm forming a part of the walls of the pressure chambers, and a plurality of piezoelectric actuators each coupled with a part of the diaphragm to form a vibrating member. The vibrating member deforms to generate a pressure wave in the ink filled within the pressure chamber, the acoustic capacitance of the vibrating member being set at 2.0×10−20 m5/N or higher.
