Method for manufacturing a needle-shaped body

Lyophilized drug solution therein to provide a needle-like member filled. Needle portion on one surface of the substrate comprises a (102), prepared needle body (10) comprising a hollow hole (103) in the needle-like portion. Then, after the water repellent treatment on the tip of the needle-like portion (102), the needle body (10) and the chemical solution was placed under reduced pressure, the bore (103) and chemical liquid spicules (10) contacting the surface, by a hollow hole (103) and atmospheric pressure while in contact with the liquid surface of the chemical liquid spicules (10) (first pressure), filling a drug solution into the hollow hole (103) to. Thereafter, freeze-drying the drug solution filled in the hollow bore (103).
