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.
