Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an inkjet applicator that easily detects the correct quantity of liquid drops discharged by using a quartz sensor, and adjusts the discharge quantity for each nozzle. SOLUTION: An inkjet application quantity measuring device 11 has the quartz sensor 21, an oscillator 22, a frequency counter 23, a mass calculator 24, and a control adjustment device 25. The frequency counter 23 counts the frequency of the output signal of the oscillator 22 caused by the impact of the liquid drops by the quartz sensor 21, and the mass calculation device 24 calculates the mass of a liquid drop on the basis of a frequency change. The control adjustment device 25 judges whether the mass is a value within a permitted range, and calculates a correction value of a driving voltage to drive a piezoelectric element discharging liquid drops and outputs the correction value as correction information to a control device 9 when the mass is a value without the prescribed range.
