[Object] To provide a liquid material applicator, an application method, and a program which can solve the problems, such as a delay in the response time of a liquid material and variations in viscosity over time, without preparing many items of control data in advance. [Solving Means] A liquid material application method for continuously applying a liquid material to a work piece by relatively moving the work piece and a screw type dispenser, which is opposed to the work piece, at a constant speed with the liquid material discharged in a non-constant amount, the method including a response time calculating step of, prior to the start of application, calculating a response delay time generated when the discharge amount of the liquid material is changed, wherein the response time calculating step includes a first sub-step of transmitting a signal for changing the discharge amount to the dispenser during the application in which a relative moving speed is held constant, and storing the time of the signal transmission, a second sub-step of calculating the time at which the discharge amount starts to be changed, by measuring the applied liquid material, and storing the calculated time, and a third sub-step of storing a differential value between the time stored in the first sub-step and the time stored in the second sub-step as the response delay time generated when the discharge amount is changed. An applicator and a program are also provided.
