摘要:
Provided is an inspection device for a liquid ejecting head including: a first vibration plate which is positioned at a position opposite to the nozzle openings of the liquid ejecting head for ejecting a liquid from the nozzle openings such that the liquid ejected from the nozzle openings of the liquid ejecting head lands thereon; a first piezoelectric element bonded to the first vibration plate; and a detecting unit which is connected to the first piezoelectric element so as to detect an electrical variation in the first piezoelectric element, wherein the detecting unit inspects the ejection state of the nozzle openings based on a voltage variation in the first piezoelectric element by the liquid landing onto the first vibration plate.
