PROBLEM TO BE SOLVED: To provide a discharge inspection device capable of reliably avoiding erroneous detection due to that detection output is buried in noise even when the noise of a maximum level occurs during inspection.SOLUTION: A discharge inspection device 21 for detecting that droplets are discharged from a plurality of nozzles, includes determination means for measuring an amount of electrical change in a state of not discharging the droplets to determine whether or not a maximum value of the measured value is less than or equal to a target value set in advance. |
