Abstract

Provided are a manufacturing method of a plate precursor having a plurality of needle-like protrusions and a manufacturing method of a microneedle array, which make it possible to manufacture a plate precursor within a short period of time. A manufacturing method of a plate precursor having a needle-like protrusion includes: a preparation step of preparing a cutting tool including at least one blade conforming to an external shape of the needle-like protrusion, and a base material; and a cutting step of cutting the base material by rotating the cutting tool about a tool axis of the cutting tool and revolving the cutting tool around an axis of the needle-like protrusion to be formed on the base material to form the needle-like protrusion having a shape conforming to a shape of the cutting tool.
