Abstract:
1. An inkjet recording apparatus comprising: a passage unit in which formed are a plurality of individual ink passages each leading to a nozzle via a pressure chamber; an actuator unit fixed to the passage unit, the actuator unit comprising a plurality of individual electrodes related to the respective pressure chambers, a common electrode, a piezoelectric layer interposed between the plurality of individual electrodes and the common electrode, and a plurality of individual lands positioned on a bonding face of the actuator unit opposite from a fixing face of the actuator unit fixed to the passage unit, the plurality of individual lands being electrically connected to the respective individual electrodes; a flat flexible substrate comprising a plurality of output terminals bonded to the respective individual lands, and a check terminal bonded to the bonding face of the actuator unit; a drive signal outputting unit which outputs drive signals to be supplied to the plurality of individual electrodes via the plurality of output terminals; a measuring unit which measures an electrical characteristic with respect to the check terminal; and a judging unit which judges, on the basis of a measurement result of the measuring unit, whether or not the check terminal has been peeled off from the bonding face of the actuator unit.
