A dispense for dispensing a liquid on a substrate is provided, including a nozzle through which to dispense on the substrate the liquid contained in a syringe, moving relative to the substrate, a valve unit for controlling dispensing of the liquid through the nozzle, including a valve which is opened and closed to control a flow of the liquid from the syringe to the nozzle and a valve controller controlling opening and closing operation of the valve, and a temperature-maintaining unit maintaining a temperature of the liquid passing the valve at a preset temperature. The present invention provides an advantage of dispensing a constant amount of liquid with no effect of a change in temperature on viscosity of the liquid.
