In an embodiment, a liquid droplet ejecting head includes sequentially in a laminated manner: a nozzle substrate; an ink tank substrate; a liquid supply substrate; and a frame substrate. The nozzle substrate is formed so that at least three or more nozzle rows are arranged in a direction intersecting a longitudinal direction of the nozzle row; the driving circuit member is provided to oppose to an outer surface of the frame substrate so as to correspond to a region between two adjacent nozzle rows located at the 4N+2-th position and the 4N+3-th position (N is 0 or a natural number); and the driving circuit member is commonly used to drive the electro-mechanical converting element and to drive the electro-mechanical converting element used for another one or two nozzle rows adjacent to at least one of the two nozzle rows. |
