An inkjet recording head allowing a high driving efficiency and preventing a variation in the driving efficiency is disclosed. An piezoelectric actuator is provided for each ink nozzle and has a driving section disposed in an area of an ink pressure chamber, an electrode pad section, and at least one bridge section connecting the driving section and the electrode pad section. The pressure chamber has a plane shape having an aspect ratio approximately equal to 1, and the bridge section has a width of a connection area to the driving section set smaller than a width of a connection side of the driving section.
