To provide a liquid droplet discharging device which forms the electrical connection to an electromechanical transducer connected to a metal diaphragm plate in an ink-jet printhead structure.
The droplet discharging device 20 is provided with a diaphragm layer 137 arranged on a fluid channel layer 131, a rough-surfaced adhesion region 137A, which is formed on the surface of the diaphragm layer 137, a thin-film circuit 138, which is arranged on the adhesion region 137A and has a conformal and raised contact region 191, and a plurality of the electromechanical transducers 139. The electromechanical transducer 139 is connected so as to adhere to the conformal and raised contact region 191 by the concavo-convex contact formed between the conformal and raised contact region 191 and the electromechanical transducer 139. The electromechanical transducer 139 is electrically connected to the conformal and raised contact region 191.
