Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for producing an acicular body capable of easily producing an acicular body while preventing damaging in an intaglio.SOLUTION: Provided is a method for producing an acicular body 1 provided with a substrate 11 and an acicular part 13 projected from either face 11a of the substrate 11, including: a first step of feeding an acicular part formation solution containing a material for forming the acicular part 13 on the acicular body intaglio 3 having a recessed part with a shape corresponding to the acicular part 13; a second step of removing a liquid component from the acicular formation solution fed to the surface the acicular body intaglio 3 so as to be solidified to form a solidified body 4; a third step of cutting the solidified body 4 to pre-set shape and size to form the acicular body 1; and a fourth step of removing the formed acicular body from the acicular body intaglio 3. In the third step, the solidified body 4 is cut using a molding fixture 5 heated to a pre-set temperature. 【課題】凹版に傷がつくことを防ぎつつ、針状体を簡易に製造することを可能とした針状体の製造方法を提供する。【解決手段】基板11と、この基板11の一方の面11aから突起した針部13とを備える針状体1の製造方法であって、針部13に対応した形状の凹部を有する針状体凹版3上に、針部13を形成するための材料を含有する針部形成溶液を供給する第1工程と、針状体凹版3上に供給された針部形成溶液から液性成分を除去し固化させて固化体4を形成する第2工程と、固化体4を予め設定した形状及び大きさに断裁して針状体1を形成する第3工程と、形成した針状体1を針状体凹版3から取り外す第4工程とを備える。第3工程では、予め設定した温度に加熱した成形冶具5を用いて固化体4を断裁する。【選択図】図9
