The present invention relates to an electrode structure in air disinfection devices. To this end, a negative electrode is made into a single polarity electrode made of a carbon fiber, while a positive electrode is processed into the single polarity electrode made of the carbon fiber. Voltage is then applied to the negative electrode and the positive electrode respectively. According to the present invention, it is possible to remove contaminants while killing bacteria by an electric field on a net.음전극을 탄소섬유의 단일 극성의 전극으로 만들고, 양전극도 탄소섬유의 단일 극성의 전극으로 만들되, 음전극과 양전극에 각각 전압을 인가시켜 공기를 소독하는 장치의 전극 구조에 관한 것이다.
