Abstract

A method of manufacturing a needle-shaped body includes forming a needle-shaped body precursor such that the needle-shaped body precursor has a base portion and a needle-shaped portion on the base portion, and that the needle-shaped portion has a portion which contacts the base portion and has a form of a polygon, producing a needle-shaped body original plate by forming a curved surface portion in at least a portion of an apex portion of the polygon in a junction portion at a boundary between the base portion and the needle-shaped portion, producing a resin plate by transfer molding with the needle-shaped body original plate such that the resin plate has a concave pattern corresponding to the needle-shaped portion and the curved surface portion, and producing a needle-shaped body by transfer molding with the resin plate such that the needle-shaped body has a transferred needle-shaped portion and a transferred curved surface portion.
