Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for manufacturing a microneedle made of resin.SOLUTION: A method for manufacturing a minute needle of a desired size includes using a liquid discharge device and a multiple string nozzle with a fine internal diameter, discharging molten resin to a base plate equal to or more than one time, and stretching the adhered molten resin to form the minute needle. The minute needle of a microneedle thus obtained has a resin layer of one stage or a plurality of stages, and the layer forms the extension type minute needle integrated as a whole. The method for manufacturing the microneedle includes manufacturing the minute needle by discharging molten resin to a base plate equal to or more than one time, and stretching the adhered molten resin. The microneedle having the characteristic minute needle obtained by the manufacturing method is also provided. 【課題】樹脂製のマイクロニードルの製造方法を提供する。【解決手段】液体吐出装置と微細な内径の多連ノズルを使用して、熔融樹脂を基板に１回以上吐出させ、密着した溶融樹脂を引き伸ばして微小針を形成することにより、所望のサイズの微小針を製造する方法であって、得られたマイクロニードルの微小針は、１段又は複数段の樹脂層を持ち、それが全体として一体となった伸展型の微小針を形成している。本発明は、熔融樹脂を基板に１回以上吐出させ、密着した溶融樹脂を引き伸ばして微小針を製造することを特徴とするマイクロニードルの製造方法とこの製造方法によって得られた特徴的な微小針を持つマイクロニードルに関するものである。【選択図】図５
