Abstract: A method of manufacturing an acicular body including a support substrate and a needle formed on the support substrate, includes: supplying a needle forming solution onto an intaglio plate having a recess that has a shape corresponding to the needle; disposing a film on the needle forming solution; compressing the needle forming solution from above the film such that the needle forming solution is moved into the recess; and removing a liquid component from the needle forming solution inside the recess such that the needle forming solution is solidified and that the needle is formed.

Abstract: A method for manufacturing a needle-shaped body, including supplying a first aqueous solution to an intaglio plate, supplying a second aqueous solution to the intaglio plate, drying the first and second aqueous solutions in the intaglio plate such that a dried body is formed on the intaglio plate, and separating the dried body from the intaglio plate such that a needle-shaped body including a needle-shaped projection and a support base which supports the needle-shaped projection is obtained. The intaglio plate includes a recess corresponding to the needle-shaped projection, the first aqueous solution is supplied to fill at least a portion of the recess, the first aqueous solution and the second aqueous solution are immiscible, the first aqueous solution forms a projection side layer in the needle-shaped body, and the second aqueous solution forms a support base side layer on the projection side layer in the needle-shaped body.
