摘要:
Provided are: a needle-shaped body production method that, in a step for molding a needle-shaped body using a resin plate, enables plate durability to be improved when releasing the needle-shaped body from the resin plate, and enables the productivity of the needle-shaped body to be improved; and a needle-shaped body. This needle-shaped body production method includes: a step for forming a needle-shaped body precursor (106) in which needle-shaped parts (105) are provided on a substrate part (104), and the portion of the needle-shaped parts (105) that comes into contact with the substrate part (104) is a polyhedral body; a step for creating a needle-shaped body original plate by forming curved parts (110), at at least a portion of the vertices of the polyhedral bodies, in a connection section (107) which is the interface between the substrate part (104) of the needle-shaped body precursor (106) and the needle-shaped parts (105); a step for creating the resin plate by transfer molding which uses the needle-shaped body original plate, the resin plate including an uneven pattern corresponding to the needle-shaped parts (105) and the curved parts (110) of the needle-shaped body original plate; and a step for creating the needle-shaped body by transfer molding which uses the resin plate, the needle-shaped body including needle shaped parts and curved parts which were transferred from the needle-shaped parts (105) and the curved parts (110).La présente invention concerne un procédé de production de corps en forme d'aiguille qui, lors d'une étape de moulage d'un corps en forme d'aiguille au moyen d'une plaque de résine, permet d'améliorer la durabilité de la plaque lors de la libération du corps en forme d'aiguille depuis la plaque de résine, et d'améliorer la productivité du corps en forme d'aiguille ; et un corps en forme d'aiguille. Ce procédé de production de corps en forme d'aiguille comprend les étapes suivantes : une étape de formation d'un précurseur de corps en for
