The present invention relates to a dissolvable micro needle, which comprises a micro needle which is administered in the skin by puncturing the skin using a micro needle, a target material in the micro needle is administered into the skin by dissolving the micro needle when the micro needle is inserted through the skin, To a micro needle patch. The use of the micro needle according to the present invention has an appropriate mechanical strength, viscosity and hardness and can be easily inserted into the skin without any change in shape such as bending or breaking, and effective perforation of the skin is possible. In addition, since the microneedles according to the present invention dissolve through the perforated skin, the excellent skin permeability of the target material is shown. Therefore, even when the micro-needle according to the present invention does not need to be pressurized with a strong force, . |
