| abstract | The disclosed method for manufacturing a microneedle according to the present invention includes the steps of providing a body portion; And a coating step of coating the chemical solution on the body portion; Including, wherein the body portion is provided with a stepped area between the front end and the rear end, the coating step is coated only on the stepped area, the preparing step, the aspect ratio of the width to the height of the body portion is 2.5 to Adjust the aspect ratio of the body portion in the range of 3.3, and the coating step reduces the aspect ratio of the body portion than in the preparing step, so that the mechanical strength in the coating step is increased than in the preparing step, and the body portion is the After penetrating the skin and penetrating the chemical, the aspect ratio is increased again and the mechanical strength of the body is reduced to be lower than the original strength before coating, and the preparing step provides the body with a polymer material, and the polymer material includes at least one of polypropylene (PP) and polyamide (polyamide)-based synthetic polymer compounds. According to this configuration, the aspect ratio is increased again after the microneedles penetrate the skin, thereby preventing reuse. |
