    摘要： Provided is a method of manufacturing a hollow microneedle structure. The method includes coating a hollow core having a predetermined section and being long in a lengthwise direction with a coating solution, and solidifying the coating solution to form a coating layer, depositing a metal seed layer on the coating layer, plating the seed metal layer with a metal to form a plated layer, cutting the hollow core having the plated layer at an inclination angle with respect to the lengthwise direction to form a surface inclination, and removing the hollow core and the coating layer to form a hollow. Thus, the hollow microneedle structure can be manufactured to have such diameter, length, hardness, and inclination angle as to minimize pain. By use of the hollow core, the microneedle structure can have vertical microneedles with a uniform inner diameter.
