It is an object of the present invention to provide a needle-shaped body manufacturing method and a manufacturing apparatus that can be filled up to the tip of the protrusion. A method for manufacturing a support substrate and a needle-like body having a needle-like protrusion on one surface of the support substrate, wherein the needle-like body forming material is used as a solvent for an intaglio plate having a recess corresponding to the protrusion. A supply step of supplying a dissolved or dispersed needle-like body forming liquid； a drying step of drying the needle-like body forming liquid in the intaglio to form a needle-like body； and a peeling step of peeling the needle-like body from the intaglio And the supply step is performed under a pressure environment of 0.05 MPa or less, and the drying step is performed under a pressure environment higher than the pressure environment of the supply step. It was set as the manufacturing method of the body.突起部先端まで充填可能な針状体製造方法及び製造装置を提供することを課題とする。 支持基板と、該支持基板の一方の面に針状の突起部を備える針状体の製造方法であって、前記突起部に対応した凹部を備える凹版に対し、針状体形成材料を溶媒に溶解または分散させた針状体形成液を供給する供給工程と、前記凹版内の針状体形成液を乾燥し針状体とする乾燥工程と前記凹版から針状体を剥離する剥離工程とを備え、かつ、前記供給工程が、０．０５ＭＰａ以下の圧力環境下でおこなわれ、かつ、前記乾燥工程が前記供給工程の圧力環境下よりも高い圧力環境下でおこなわれることを特徴とする針状体の製造方法とした。
