Disclosed are a liquid-jet recording head and a liquid-jet recording apparatus, which are capable of retaining a fine liquid ejecting characteristic and obtaining a stable liquid ejecting characteristic. The liquid-jet recording head, which is provided with a passage-forming substrate formed with pressure generating chambers 12 to communicate with nozzle orifices, and piezoelectric elements provided on one side of the passage-forming substrate through a vibration plate to generate pressure changes inside the pressure generating chambers, includes an insulation layer continuously provided at least in a region opposing to the vicinity of longitudinal end portions of the piezoelectric elements along a direction of arrangement of the piezoelectric elements, the insulation layer also having a penetrated portion in a region opposing to a common electrode provided in common to the plurality of piezoelectric elements, and a connective wiring layer continuously provided on the insulation layer to be electrically connected to the common electrode via the penetrated portion. Accordingly, a resistance value of the common electrode is substantially reduced.
