NEEDLE-SHAPED BODY AND MANUFACTURING METHOD FOR NEEDLE-SHAPED BODY

摘要

An object of the present invention is to provide a needle-like body that is easy to peel. A method for manufacturing a needle-like body having a needle-shaped protrusion and a supporting substrate supporting the protrusion, comprising: supplying an aqueous solution of a protrusion-side layer forming material to a concave plate having a concave portion corresponding to the protrusion, and And a step of supplying an aqueous solution of the supporting substrate side layer forming material, a step of drying the aqueous solution in the intaglio to form a needle body, and a step of peeling the needle body from the intaglio plate, and further comprising an aqueous solution of the protrusion side layer forming material. , The aqueous solution of the supporting substrate side layer forming material was a liquid-liquid dispersion system.
