Title: NEEDLE BODY MANUFACTURING METHOD AND MANUFACTURING DEVICE
Abstract:
Provided is a needle body manufacturing method with which a needle body can be manufactured inexpensively and under ordinary pressure, while the inclusion of air bubbles is curbed. The method for manufacturing a needle body, which has a support substrate and needle sections provided on the support substrate, comprises the following: a first step for supplying a needle section formation solution (20a), containing a needle section material for forming the needle sections, onto an engraved plate (30) having recesses (30a) of a shape corresponding to the needle sections; a second step for disposing a permeable film (10A) onto the needle section formation solution, applying pressure to the needle section formation solution from above the permeable film, and causing the needle section formation solution to move into the recesses; and a third step for removing a liquid component from the needle section formation solution inside the recesses and solidifying the needle section formation solution to form the needle sections.
