Method of fabricating a template for a concave array mold, a concave array mold and a needle array sheet

摘要

A method of fabricating a template (14) for a concave array mold (30) having a plurality of recesses of a high aspect ratio includes arranging a plurality of needles (10) in a mutually separated state and fixing the plurality of the arranged needles (10). This method allows a template for a concave array mold having a high aspect ratio structure to be easily and inexpensively fabricated. Further, the thus fabricated template can be used to easily and inexpensively fabricate a concave array mold. Furthermore, a needle array sheet can be fabricated by injecting and fixing a resin solution into the concave array mold (30) and separating the cured resin solution from the concave array mold (30).
