The present invention relates to a needle electroporator to inject correct amount of medicine into skin of a patient at correct depth, so as to maximize effects of the medicine. The needle electroporator comprises: a needle frame having a front-end outlet of a needle, which penetrates inside the needle frame, projecting out towards the front, a rear-end inlet opened outside a rear surface, and a stepped partition wall provided in a closed shape outside the rear surface to allow the rear-end inlet to locate inside the partition wall； a needle cover having a space toward the inner portion formed in the rear side, a needle guide hole formed in a front surface to allow a needle to penetrate therethrough while communicating with the space, and an insertion hole formed on a lower surface； a contact point printed circuit board (PCB) receiving power from a power supply unit, having a contact hole on a front surface to allow the needle to penetrate, and applying a positive or negative polarity according to the power supply to the needle which penetrates the contact hole； and a needle hub having an insertion unit towards the inside formed in the front, an injection part formed outside the rear surface to be connected to a syringe, a path formed inside the rear surface to be inserted into the inside of the partition wall of the needle frame which is located inside the insertion unit while communicating with the injection unit, and a part thereof in the front fitted in the space of the needle cover while the contact point PCB and the needle frame are in a state of being sequentially inserted in the insertion unit.본 발명은 니들 일렉트로포레이터에 관한 것으로서, 내부를 관통하는 니들의 선단 출구는 전방을 향하여 돌출되고 그 후단 입구는 후면 바깥쪽에서 개방되며 후면 바깥쪽에는 단턱진 구획벽이 폐쇄형태로 구비되어 상기 니들의 후단 입구가 상기 구획벽 내부에 위치하는 니들 프레임과, 후방에는 내부를 향해 공간부가 형성되고 전면에는 공간부와 연통되면서 니들이 관통되는 니들 안내구가 형성되며 저면에는 끼움구가 형성된 니들 커버와, 전원 공급장치로부터 전원이 공급되며 전면에는 상기 니들이 관통될 수 있도록 접점공이 관통 형성되고 전원의 공급에 따른 양극 또는 음극을 접점공에 관통된 니들에 인가시켜주는 접점 PCB 및 전방에는 내부를 향해 끼움부가 형성되며 후면의 바깥쪽에는
