Disclosed is an outside electrochromic mirror system for a vehicle, comprising: an electrochromic mirror including transparent glass for passing light, a liquid crystal film attached to one surface of the transparent glass and having electrodes printed on both surfaces, a reflective film attached to one surface of the liquid crystal film and reflecting the light having passed through the transparent glass, and a circuit board attached to one surface of the reflective film; a controller for generating a PWM signal; and a driver for generating a voltage according to the PWM signal and applying the generated voltage to the electrochromic mirror, wherein through holes are formed at the predetermined positions of the liquid crystal film, the reflective film and the circuit board, an optical sensor is arranged at the through hole formed on one surface of the circuit board, the amount of light is received from the optical sensor attached to the electrochromic mirror, and a voltage to be applied to the electrochromic mirror is controlled based on the received amount of light to adjust the transmittance of the electrochromic mirror. Therefore, provided is an outside electrochromic mirror system for a vehicle, which prevents a driver from being dazzled.
