PURPOSE: Provided is a micro needle easy to manufacture at a low cost and capable of reducing the pain when collecting a sample from a patient. CONSTITUTION: A micro needle(80) for collecting a biological liquid while minimizing the intrusion to a body(75) and supplying a drug or other components through the skin while minimizing the intrusion to the body(75), comprises a base(70) at a proximal end, an apex at a distal end and an open bore extended between the proximal end and the distal end to carry the liquid. The structure forms a structural axis crossing the bore axis formed by the open bore. The intersection between the axes, which is located in a point under the apex of the micro needle, forms a sharp apex at a distal end(58) of the micro needle(80) to form the whole shape of the distal end(58) of the micro needle(80). |
