Provided is a method for producing a needle-like body, which can produce a needle-like body at a low cost under normal pressure while suppressing the mixing of bubbles. A method for producing a needle-like body comprising a support substrate and a needle part provided on the support substrate is a method for producing a needle part material for forming a needle part on an intaglio plate 30 having a concave part 30a having a shape corresponding to the needle part. A first step of supplying the needle portion forming solution 20a to be contained； and a breathable film 10A is disposed on the needle portion forming solution, and the needle portion forming solution is pressurized from above the breathable film so as to be in the recess. And a third step of forming the needle part by removing the liquid component from the needle part forming solution in the recess to solidify the needle part forming solution.気泡の混入を抑制しつつ、常圧下で安価に針状体を製造することができる針状体の製造方法を提供する。支持基板と、支持基板上に設けられた針部とを備えた針状体の製造方法は、針部に対応した形状の凹部３０ａを有する凹版３０上に、針部を形成する針部材料を含有する針部形成溶液２０ａを供給する第１工程と、針部形成溶液上に通気性フィルム１０Ａを配置し、通気性フィルム上から針部形成溶液を加圧して凹部内に前記針部形成溶液を移動させる第２工程と、凹部内の針部形成溶液から液性成分を除去して針部形成溶液を固化させ、針部を形成する第３工程とを備える。
