A liquid-droplet ejection head includes a nozzle substrate, a chamber substrate, a liquid supply substrate, a frame substrate, a driving circuit member, and wire members. The nozzle substrate includes nozzles. The chamber substrate is formed on the nozzle substrate and includes liquid chambers, diaphragms, and electro-mechanical transducers. The liquid supply substrate is formed on the chamber substrate and includes liquid supply channels. The frame substrate is formed on a first face of the liquid supply substrate opposite a second face of the liquid supply substrate formed on the chamber substrate. The driving circuit member that drives the electro-mechanical transducers is mounted on the frame substrate. The wire members connect the electro-mechanical transducers to the driving circuit member. A voltage applied to the electro-mechanical transducers through the wire members deforms the electro-mechanical transducers and the diaphragms to generate pressure in the liquid chambers.
