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: A microneedle including a projection having a through hole formed in the projection in a direction that the projection extends, and a tubular member having an end surface configured to support the projection when the end surface is pressed against a skin and a fluid is supplied through the through hole of the projection to the skin. The projection has a length H along the direction that the projection extends and the supporting surface has an area S such that a ratio of S/H is in a range of from 2.1 to 10.5.
