PROBLEM TO BE SOLVED: To provide a manufacturing method for a needle-like body by which tip ends of needle-like parts of the needle-like body are stable in shape.SOLUTION: A needle-like body 1 includes: needle-like parts having a needle-like shape； and a support substrate for supporting base ends of the needle-like parts. A concave plate 10 is prepared which includes recess parts 1004 corresponding to the needle-like parts on a surface 1002. The concave plate 10 that is manufactured is exposed to a solvent vapor 12 of a needle-like body formation liquid. Thus, a sticking step is made in which a solvent 16 for dissolving a needle-like body formation material that forms the needle-like body 1 is made to stick to the surface 1002 that has the recess parts 1004. A filling step is performed in which the needle-like body formation liquid 18 containing the solvent 16 and the needle-like body formation material is filled into the surface 1002 having the recess parts 1004, of the concave plate 10. A needle-like body formation step is performed in which the needle-like body 1 is formed by drying and solidifying the needle-like body formation liquid. A peeling step is performed in which the needle-like body 1 is peeled from the concave plate 10, to provide the needle-like body 1.【課題】針状部先端の形状が安定した針状体の製造方法を提供する。【解決手段】針状体１は、針状形状を有する針状部と、針状部の基端を支持する支持基板とを備えている。表面１００２に針状部に対応した凹部１００４を備える凹版１０を用意する。作製した凹版１０を針状体形成液の溶媒蒸気１２に晒す。これにより凹部１００４を含む表面１００２に針状体１を形成する針状体形成材料を溶解する溶媒１６を付着させる付着工程がなされる。溶媒１６と針状体形成材料とを含む針状体形成液１８を凹版１０の凹部１００２を含む表面１００４に充填する充填工程がなされる。針状体形成液を乾燥固化させることで針状体１を形成する針状体形成工程がなされる。針状体１を凹版１０から剥離する剥離工程がなされ、針状体１が得られる。【選択図】図３
