The present invention relates to a total reflection type rain sensor using a mirror, which is attached to a glass of a vehicle to detect raindrops falling onto the glass of the vehicle and outputs a signal capable of controlling speed and cycle of a wiper of the vehicle according to the amount and falling frequency of raindrops detected. More specifically, the total reflection type rain sensor using a mirror according to the present invention comprises a light emitting unit, an adhering portion, a light receiving unit and a control unit and is attached to the glass of a vehicle to detect raindrops falling onto the glass of the vehicle, the rain sensor being characterized in that the light receiving unit receives light that is emitted from the light emitting unit to be incident on the glass of the vehicle and totally reflected from the glass of the vehicle and outputs a signal regarding an amount of the light received; and the control unit communicates with the vehicle and stores a predetermined threshold value allowing the wiper of the vehicle to operate, wherein the control unit receives the signal from the light receiving unit, analyzes the amount of raindrops corresponding to the amount of light, and actuates the wipers when the amount of raindrops exceeds the threshold value.
