Patent ID: 8383027

Claim:
A method of fabricating a needle array sheet comprising: a template fabrication step of fabricating a template by arranging a plurality of needles in a mutually separated state and fixing the arranged plurality of needles; a concave array mold fabrication step of fabricating a concave array mold by curing a mold resin solution in a state in which at least the plurality of needles of the template are immersed in the mold resin solution having a contact angle of more than 90 degrees with respect to a root portion of the needle and separating the cured mold resin solution from the template; a resin injection step of injecting a resin solution into a sheet fabrication mold including the concave array mold fabricated by the concave array mold fabrication step; a resin curing step of curing the resin solution injected in the resin injection step; and a separation step of separating the resin solution cured in the resin curing step.
