Disclosed are a micro needle and a micro needle device. The micro needle improves medical substance delivery effectiveness and prevents breakage of a needle. The micro needle includes a needle and a body. The needle includes an inclination part, a straight part, and a recess. The inclination part has an inclined outer wall. The straight part has a straight outer wall. The recess has a predetermined depth and extends along the outer wall of the inclination part or the straight part. The body is coupled to the needle to move or support the needle. The micro needle device includes a micro needle head, an infrared ray generator, and a power supply. Front ends of micro needles are exposed to the outside of the micro needle head. When the micro needles are pressed against a skin, the micro needles reach the dermis of the skin. The infrared ray generator generates infrared rays or far-infrared rays that are irradiated on the skin through the inside or outside of the micro needles. The power supply supplies energy required for the infrared ray generator to generate infrared rays or far-infrared rays. |
