<；P>；PROBLEM TO BE SOLVED: To provide a method for manufacturing a microneedle the center of which is holed. <；P>；SOLUTION: In this method for manufacturing a microneedle, a board is holed and the hole is filled with a bulking agent. Then, a part of the bulking agent is deformed to etch the board. By this constitution, a part of the bulking agent is used as a mask to etch the board, and therefore, the holed microneedle can be shaped in such a manner that the position of the area of the protuberance of the microneedle, and the position of the area of the hole may correspond to each other by one to one without slipping from each other. Thus, the microneedle the center of which is holed can suitably be manufactured. <；P>；COPYRIGHT: (C)2009,JPO&INPIT
