A needle shaped body filled with freeze-dried drug solution is provided. A needle shaped body (10) which includes a needle shaped portion (102) on one surface of a substrate is provided with the needle shaped portion having a hollow hole (103). After a water-repellent treatment is applied on the tip of the needle shaped portion (102), the needle shaped body (10) and the drug solution are placed under a reduced pressure, and then the hollow hole (103) of the needle shaped body (10) and a liquid surface of the drug solution are brought into contact with each other. While the hollow hole (103) of the needle shaped body (10) and the liquid surface of the drug solution are brought into contact with each other, the pressure is released to atmospheric pressure (first pressure) so that the drug solution is filled into the hollow hole (103). After that, the drug solution filled in the hollow hole (103) is freeze-dried.
