PROBLEM TO BE SOLVED: To improve yield of manufacturing a recording head by reducing vibration different for every inkjet recording head and every nozzle, and to highly accurately stabilize the ejection of ink droplets without enlarging the size of the inkjet recording head. SOLUTION: The inkjet recording head comprises a pressure chamber 3 for accumulating ink, a pressure generating means for generating pressure fluctuation within the pressure chamber by application of an electric signal, a diaphragm 7 which forms at least a part of wall face of the pressure chamber and are connected to the pressure generating means by an elastic material, a restrictor 5 being a flow channel for supplying ink to the pressure chamber, a housing having a common ink flow channel for supplying ink to the restrictor, and a nozzle 1 for ejecting ink droplets from the pressure chamber. The inkjet recording head is provided with an opposite phase vibration generating means for generating vibration with the phase opposite to the vibration of the pressure generating means.
