An application method in which an application pattern (141, 142) for applying a liquid material onto a workpiece is prepared, wherein the liquid material is ejected from a nozzle of an ejection unit while the nozzle and a workpiece are moved relative to each other, and the liquid material is applied in a specific application amount to the workpiece, the specific application amount means an amount of the liquid material required for drawing the application pattern (141, 142), the application method including: an initial parameter setting step of specifying a pulse signal of a predefined frequency, which is based on a mechanical response characteristic of the ejection unit for ejecting the liquid material and characteristics of the liquid material, and having a total pulse number corresponding to the specific application amount including at least one ejection pulse in which the pulse signal is in the on state and zero or more pause pulses, in which the pulse signal is in the off state, wherein an ejection amount, which corresponds to the number of ejection pulses, is adjustable by increasing or decreasing the number of pause pulses in the total pulse number; a step of starting the application of the liquid material; a step of setting a correction period at which an ejection amount is to be corrected, wherein the correction period is set taking into consideration a viscosity change of the liquid material; a correction amount calculation step comprising at least one of measuring, after the preset correction period, the ejection amount from the nozzle, and calculating a correction amount for the ejection amount based on a difference between the weight of the liquid material measured after ejecting the liquid material for a certain time and the proper weight for the specific application amount, or measuring, after the preset correction period, the ejection time taken until reaching the proper weight of the liquid material ejected from the nozzle, and calculating a correction amount for the ejection amount based on a difference between the measured ejection time and the actual ejection time in a just preceding correction amount calculating step; an ejection amount correction step of correcting the ejection amount by adjusting the number of ejection pulses and the number of pause pulses included in the pulse signal on the basis of the correction amount calculated in the correction amount calculation step, wherein the total pulse number and the frequency of the pulse signal is kept constant while the numbers of the ejection pulses and the pause pulses are changed;
