An ejection inspecting device is operable to inspect an ejection state of a fluid ejection device operable to eject a fluid. The ejection inspecting device includes: at least one pair of electrodes, disposed so that the fluid can pass; an oscillation executing unit, connected to the electrodes, and operable to electrically oscillates; an oscillation detecting unit, operable to detect an oscillation state oscillated by the oscillation executing unit by counting the number of oscillations during a predetermined period; and a control unit, operable to detect whether the fluid has been ejected from the fluid ejection device based on the number of oscillations detected during the predetermined period during which the fluid has not been ejected, and based on the number of oscillations detected during the predetermined period during which the fluid ejected therefrom has passed near the electrodes.
