<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing a microneedle, capable of easily manufacturing a microneedle with a through-hole, and a microneedle substrate manufactured by such a method of manufacturing a microneedle. <P>SOLUTION: By imparting heat or optical energy to a hardening resin and controlling the energy, the outer peripheral part of the hardening resin is turned to a hardened part and the inner peripheral part is turned to a non-hardened part. Then, by removing the hardening resin at the non-hardened part, a microneedle having a through-hole is obtained. <P>COPYRIGHT: (C)2011,JPO&INPIT |
