The liquid droplet ejection apparatus includes a liquid holding material which has three-dimensional voids communicating three-dimensionally with one another at least up to a liquid droplet ejection surface and an array of a plurality of ejection devices each of which applies ejection energy to a part of liquid held in the thee-dimensional voids of the liquid holding material, thereby ejecting fine liquid droplets from the liquid droplet ejection surface, wherein the fine liquid droplets are ejected in accordance with each of the ejection devices of the array. The inkjet recording head uses the liquid droplet ejection apparatus for an ink ejection means as it is or in a form of a one-dimensional, two-dimensional or three-dimensional arrangement. Accordingly, a new liquid droplet ejection apparatus and a new inkjet recording head are realized with no need of a large number of nozzles to eject liquid droplets and individual ink flow paths formed for respective nozzles, of a heater, an actuator or the like which is corresponding to each nozzle.
