Abstract
There are provided a liquid ejecting head and a liquid-ejecting recording apparatus in which it is possible to improve convenience. According to an embodiment of the present disclosure, a liquid ejecting head includes an ejecting section including a plurality of nozzles for ejecting liquid, a driving circuit that drives the ejecting section based on a printing driving signal to eject the liquid from the nozzles, a power supply path connected to the driving circuit, a detection section that acquires measurement data based on a detection result of a current flowing on the power supply path, and an arithmetic operation section that performs both an inspection of a state of the ejecting section based on the measurement data obtained by the detection section and acquisition of a parameter for ejection of the liquid.
