PROBLEM TO BE SOLVED: To provide a liquid droplet ejection head, the operation speed and quality of which are enhanced, and which can be downsized, and a liquid droplet ejector. SOLUTION: This liquid droplet ejection head 1 comprises: a nozzle array 11A with a plurality of nozzle holes 11(11a, 11b, etc.); a liquid droplet pressure chamber 2 which is equipped with a plurality of pressure chambers 2a and 2b etc. communicating with the nozzle holes 11, respectively; common liquid drop chambers 3 and 4 which communicate with the pressure chambers 2a and 2b etc. of the liquid droplet pressure chamber 2 so as to supply a liquid to the pressure chambers 2a and 2b etc., respectively; a diaphragm 7 which is formed in a part of the wall surface of the liquid droplet pressure chamber 2; and a driving means for ejecting the liquid in the liquid droplet pressure chamber 2 from the nozzle holes 11 by displacing the diaphragm 7. The plurality of common liquid droplet chambers 3 and 4, which are provided in a laminated state, communicate with the pressure chambers 2a, 2b, etc. of the liquid droplet pressure chamber 2, respectively.
