Abstract
A liquid droplet discharge head includes a nozzle substrate having a nozzle hole; a liquid chamber substrate including a liquid chamber that is in communication with the nozzle hole and a liquid introduction path; an oscillation plate forming a part of the liquid chamber; an electromechanical conversion element that is arranged on the oscillation plate and is configured to be deformed by a voltage applied from the exterior to cause the oscillation plate to deform and the liquid chamber to generate pressure so that liquid within the liquid chamber is discharged from the nozzle hole; a common liquid chamber that is in communication with the liquid chamber via the liquid introduction path and is configured to supply liquid to the liquid chamber; and a common liquid chamber forming substrate that includes a single metal plate integrated with resin to form the common liquid chamber.
