Abstract
Disclosed is a micro-needle including a tip formed using medicine that penetrates into the skin and melts therein; and at least one guide groove each in a stepped shape inward from the outer surface of the tip, and provided to the tip. The micro-needle configured as above may be used to administer a fixed quantity of medicine within a relatively short period of time. Also, since a guide space stepped based on the tip is provided to a base that supports the tip, a large amount of medicine may easily penetrate into the skin.
