본 발명의 초발수성 표면을 가진 이슬맺힘방지부재의 제조방법은, 분체도료와 폴리테트라플루오로에틸렌을 소정 비율로 혼합하는 단계, 혼합된 도료로 기판 표면에 분체도장하는 단계, 및 상기 분체도장된 기판을 열처리하는 단계를 포함한다. 본 발명의 다른 형태에 의한 초친수성 표면을 가진 이슬맺힘방지부재의 제조방법은, 기판을 전착도료에 담그고 직류 전압을 가해 전착도장하는 단계, 상기 전착도장된 기판을 열처리하는 단계; 및 상기 기판의 전착도장된 표면을 플라즈마 처리하는 단계를 포함한다. A method of manufacturing a dew formation preventing member having a super water repellent surface of the present invention comprises the steps of: mixing a particular paint and polytetrafluorethylene at a predetermined ratio; particulate painting the mixed paint on a substrate surface; and heat treating the particulate painted substrate. A method of manufacturing a dew formation preventing member having a super water repellent surface according to another aspect of the present invention comprises the steps of: immersing a substrate in an electro deposition paint, and applying a direct current to conduct electro deposition painting; heat treating the substrate that has undergone the electro deposition painting; and plasma treating the surface of the substrate that has undergone the electro deposition painting.
