<P>PROBLEM TO BE SOLVED: To mass-produce, using biodegradable resin, a microneedle which is free from a defect at the tip of the microneedle and stable in quality. <P>SOLUTION: A two-stage manufacturing method of the microneedle includes a step of firstly preparing a microneedle device structured as a lattice window and having the microneedle extending horizontally, and a step of then setting the needle to be vertical by bending the direction of the needle to 90° by a tool. Thus, the microneedle which hardly have a defect at the tip and is highly reliable in product standard can be produced. Further, the method can manufacture a microneedle which has been conventionally difficult to make. <P>COPYRIGHT: (C)2009,JPO&INPIT |
