Abstract: A method of manufacturing a microneedle including forming a plurality of first linear grooves on a substrate in parallel to one another along a first direction using grinding and forming a plurality of second linear grooves on the substrate in parallel to one another in a second direction intersecting the first direction using grinding. At least one of the forming of a plurality of first linear grooves and the forming of a plurality of second linear grooves includes forming first stage grooves using a first dicing blade; and processing the first stage grooves by tracing the first stage grooves using a second dicing blade having a side surface different from that of the first dicing blade to thereby form second stage grooves.

Abstract: The invention discloses a method of manufacturing a microneedle including the steps of forming an island etching mask having thickness distribution on a substrate, and processing the substrate into a needle by taking advantage of a difference in etching rates between the etching mask and the substrate. The invention enables to readily control a point angle and height of the manufactured needle.
