PROBLEM TO BE SOLVED: To provide a microneedle whose tip part is coated to the same height by simple equipment/steps.SOLUTION: The method for manufacturing a microneedle sheet includes: a step of preparing a stamper base material in which a first base material and a second base material are peelably stuck to each other; a step of making a stamper by forming a plurality of needle-like recessed parts penetrating the second base material by pushing a metallic mold having a plurality of needle-like projection parts on the surface from a second base material side to the stamper base material; a step of forming a plurality of needle-like projections by pouring a raw material liquid into the needle-like recessed parts followed by solidifying the raw material liquid; a step of exposing a first part as the tip part of the needle-like projection by peeling the first base material from the second base material; a step of coating a coating material on the surface of the exposed first part; and a step of peeling the plurality of needle-like projections from the second base material. |
