The present invention relates to a mirror apparatus for radiating far-infrared rays, which has a far-infrared-ray-radiating heat-emitting plate coated with resin mounted on the rear side of the mirror, wherein an insulating material having an aluminum sheet formed on the front surface thereof is mounted on the rear surface part of the far-infrared-ray-radiating heat-emitting plate, and wherein the reflective surface of the mirror is formed of a reflective material having a far-infrared ray radiation rate of 0.5 or more. The mirror apparatus for radiating far-infrared rays comprises a control part for conducting a first-step temperature control of keeping the heat-emitting surface temperature of the far-infrared-ray-radiating heat-emitting plate at 35 to 45°C so as to prevent the mirror from steaming up, and a second-step temperature control of keeping the heat-emitting temperature of the far-infrared-ray-radiating heat-emitting plate at 50 to 65°C for the function of a cosmetic mirror capable of radiating a massive amount of far-infrared radiant energy beneficial to the skin care of a user. The mirror apparatus for radiating far-infrared rays also has the function of a cosmetic mirror for radiating a massive amount of far-infrared radiant energy.COPYRIGHT KIPO 2014본 발명은, 수지로 피복된 원적외선 복사 면상발열체를 거울의 배면에 장착하되, 원적외선 복사 면상발열체의 배면부에는 알루미늄시트가 전면 형성된 단열재를 장치하고 거울의 반사면은 원적외선 방사율이 0.5이상이 되는 반사물질로 형성하고, 김서림방지를 위해 상기 원적외선 복사 면상발열체의 발열 표면온도가 35~45℃로 되는 1단계 온도제어와 사용자의 피부미용에 이로운 원적외선 복사에너지량의 다량 방사가 가능한 화장경 기능을 위해 상기 원적외선 복사 면상발열체의 발열온도가 50~65℃로 되는 2단계 온도제어를 수행하는 제어부를 구비한 원적외선 복사되는 거울장치로서, 원적외선 복사 에너지량이 다량 발산되는 화장경 기능을 함께 적용할 수 있다.
