An inkjet recording head having: a nozzle ejecting ink drops; a pressure chamber which communicates with the nozzle and in which ink is filled; a vibrating plate structuring a portion of the pressure chamber; an ink pooling chamber pooling ink to be supplied to the pressure chamber via an ink flow path; and a piezoelectric element displacing the vibrating plate. The ink pooling chamber is provided at a side of the vibrating plate opposite the side at which the pressure chamber is provided. A driving IC, which applies voltage to the piezoelectric element, is mounted on a piezoelectric element substrate which is formed so as to include the vibrating plate. Accordingly, there is provided the inkjet recording head which realizes a higher density of nozzles and an accompanying formation of wires at a fine pitch to realize higher resolution, and which can be compact.
