PROBLEM TO BE SOLVED: To provide a method for manufacturing a needle-like body which increases efficiency of medicament delivery for increasing the delivery amount.SOLUTION: A method for manufacturing a needle-like body original plate 400 having a needle-like part 101 on one surface of a base plate 100 includes the steps of: forming the cone-shaped needle-like part by finely processing the base plate; applying a repellent etching protective material 103 on the needle-like body and hardening the etching protective material; removing the etching protective material from a tip end part of the needle-like body to an intermediate part between the tip end part and a bottom surface at which the needle-like part is continuously connected to the base plate; dripping a step forming material 109 to the tip end part of the needle-like part which is exposed by removing the etching protective material; and hardening the step forming material.SELECTED DRAWING: Figure 3 |
