Abstract:
1. A liquid droplet ejecting head comprising sequentially in a laminated manner: a nozzle substrate including a plurality of nozzles; an ink tank substrate including a liquid supply substrate including a plurality of liquid supply paths respectively supplying a liquid to the ink tanks; and a frame substrate including common ink tanks communicating with each liquid supply path, wherein an electrode of a driving circuit member driving the electro-mechanical converting elements is connected to each electrode of the plurality of the electro-mechanical converting elements through an interconnection member; the nozzle substrate is formed so that at least three or more nozzle rows, each nozzle row including the plurality of nozzles, 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) in an arrangement direction among the plurality of nozzle rows arranged in the direction intersecting the longitudinal direction of the nozzle row; and the driving circuit member is commonly used
