Abstract
A liquid droplet ejecting apparatus includes a liquid ejecting module and a measurement section. The liquid ejecting module includes a pressure chamber that has a piezoelectric element and an ejecting nozzle, and a supply passage that supplies liquid into the pressure chamber, and the liquid ejecting module configured to eject, from the ejecting nozzles, liquid which is supplied to the pressure chamber through the supply passage. The measurement section measures an admittance or a phase difference between a voltage applied to the piezoelectric element and a current through the liquid ejecting module when the voltage is applied.
