Zusammenfassung:	An embodiment of the present invention provides a manufacturing method of a microneedle array, comprising: (A) a step of preparing a mold for manufacturing a microneedle including one or more concave parts by injection-molding a thermoplastic resin; and (B) a step of molding one or more microneedles by injecting a microneedle raw material into the concave part. In addition, another embedment of the present invention provides a microneedle array comprising: a mold for manufacturing a microneedle, which is manufactured by injection-molding a thermoplastic resin and includes one or more concave parts; and one or more microneedles molded by injecting a microneedle raw material into the concave part. Accordingly, the storage stability of the product can be improved. 본 발명의 일 실시예는 (A) 열가소성 플라스틱 수지를 사출 성형하여 하나 이상의 음각부를 포함하는 마이크로니들 제조용 몰드를 제조하는 단계; 및 (B) 상기 음각부에 마이크로니들 원료 물질을 주입하여 하나 이상의 마이크로니들을 성형하는 단계;를 포함하는, 마이크로니들 어레이의 제조방법을 제공한다. 또한, 본 발명의 다른 실시예는 열가소성 플라스틱 수지를 사출 성형하여 제조되며, 하나 이상의 음각부를 포함하는 마이크로니들 제조용 몰드; 및 상기 음각부에 마이크로니들 원료 물질을 주입하여 성형되는 하나 이상의 마이크로니들;을 포함하는, 마이크로니들 어레이를 제공한다.
