PROBLEM TO BE SOLVED: To reduce a liquid quantity variation of delivered liquid droplets by uniforming a displacement amount of pressure generating means mounted on a liquid jetting head. SOLUTION: A manufacturing method for a liquid jetting apparatus comprises an element driving process for driving a piezoelectric vibrator by supplying an evaluation pulse which includes a delivering element for elongating to displace the piezoelectric vibrator from an evaluation pulse generating circuit 61 to an actuator unit, a counter-electromotive force amplitude measuring process for measuring by a counter-electromotive force amplitude measuring circuit 62 an amplitude of a counter-electromotive force signal CF based on the residual vibration of the piezoelectric vibrator generated after supplying of the delivering element, and a combining process for determining a combination of actuator units to be mounted on a recording head on the basis of a size of the amplitude of the measured counter-electromotive force signal.
