PROBLEM TO BE SOLVED: To provide a method for manufacturing a needle-like body for filling to a recessed part tip end corresponding to a projection part.SOLUTION: A method for manufacturing a needle-like body includes: a first supply process for supplying a first needle-like body forming liquid to an intaglio plate in a first reduced-pressure environment; a first pressure changing process for making a pressure environment where the first needle-like body forming liquid is supplied to the intaglio plate higher than the pressure in the first reduced-pressure environment; a first drying process for drying the needle-like body forming liquid supplied to the intaglio plate; a second supply process for supplying a second needle-like body forming liquid to the intaglio plate where the first needle-like body forming liquid is filled and dried in a second reduced-pressure environment; a second pressure changing process for making a pressure environment where the first needle-like body forming liquid is supplied to the intaglio plate higher than the pressure in the second reduced-pressure environment; a second drying process for drying the needle-like body forming liquid supplied to the intaglio plate to make a needle-like body; and a detachment process for detaching the needle-like body from the intaglio plate.SELECTED DRAWING: Figure 1【課題】突起部に対応した凹部先端まで充填可能な針状体製造方法を提供することを課題とする。【解決手段】針状体の製造方法であって、凹版に対し、第1の針状体形成液を第1の減圧環境下で供給する第1の供給工程と、前記凹版に供給された第1の針状体形成液を第1の減圧環境よりも高い圧力に変化させる第1の圧力変化工程と、前記凹版に供給された針状体形成液を乾燥する第1の乾燥工程と、前記第1の針状体形成液が充填乾燥された凹版に対し、第2の針状体形成液を第2の減圧環境下で供給する第2の供給工程と、前記凹版に供給された第1の針状体形成液を第2の減圧環境よりも高い圧力に変化させる第2の圧力変化工程と、前記凹版に供給された針状体形成液を乾燥し針状体とする第2の乾燥工程と、前記凹版から前記針状体を剥離する剥離工程とを備えることを特徴とする針状体の製造方法とした。【選択図】図1
