Abstract
An inkjet head includes a substrate that defines a cavity in which ink is stored, a vibrating membrane that is supported by the substrate and that defines the cavity, and a piezoelectric device that is disposed on the vibrating membrane and that changes a volume of the cavity by displacing the vibrating membrane. A driving IC is mounted on the actuator substrate and drives the piezoelectric device.
