Disclosed are a liquid-jet head that is capable of maintaining ejection characteristics of liquid droplets, obtaining stable ink ejection characteristics, and arraying piezoelectric elements in high density, and a liquid-jet apparatus. An ink-jet recording head includes: a passage-forming substrate in which pressure generating chambers communicating with nozzle orifices are formed; and piezoelectric elements for generating pressure changes in the pressure generating chambers, which are provided on one surface side of the passage-forming substrate with vibration plate interposed therebetween. In the ink-jet recording head, a resistance reduction portion is provided to reduce a resistance of a common electrode common to the plurality of piezoelectric elements when a voltage is applied to the piezoelectric elements. The resistance reduction portion includes: common lead electrodes extracted from portions of the common electrode, which exclude both end portions in a direction where the piezoelectric elements are provided parallel, to outside regions opposite the pressure generating chambers; and connection wiring composed of a bonding wire.
