摘要： The invention regards a method of manufacturing a microneedle comprising steps of: forming a plurality of first linear grooves on a substrate (10) 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 step of forming a plurality of first linear grooves and the step of forming a plurality of second linear grooves includes: forming first stage grooves using a first dicing blade (16); processing the first stage grooves by tracing the first stage grooves using a second dicing blade (17) having a side sudace different from that of the first dicing blade (16) to thereby form second stage grooves.
