ABSTRACT:
A liquid droplet ejecting head including a piezoelectric element substrate including a diaphragm and a piezoelectric element; a liquid pool chamber that pools liquid supplied to a pressure chamber and which is provided opposite a pressure chamber filled with liquid with the piezoelectric element substrate placed in between; an upper substrate arranged so as to separate the liquid pool chamber and the piezoelectric element substrate with the piezoelectric element substrate between with a through port for supplying liquid to the pressure chamber from the liquid pool chamber formed therein; a driver that is mounted on the upper substrate and which drives the piezoelectric element; a connecting component arranged between the opposite upper substrate and the piezoelectric element substrate and which electrically connects this upper substrate to the piezoelectric element.
