Abstract: A method of manufacturing a microneedle according to the present disclosure includes a step of preparing a microneedle; a step of cooling the microneedle; and a step of inducing an endothermic reaction of the cooled microneedle, and coating the cooled microneedle with an active ingredient at least once. In accordance with such a configuration, coatability of the active ingredient can be improved due to an endothermic reaction without a separate drying process, thereby providing superior medication.
