An automatic antiglare mirror for a vehicle with its reflectivity being variably controlled by an electrochromic element includes a rear light detection circuit (12) for detecting quantity of light in the rear of the vehicle, a coloration amount control circuit (16) for controlling an amount of coloration of the electrochromic element and a response speed control circuit (34) for controlling response speed of the electrochromic element. The coloration amount control circuit (16) performs control of the amount of coloration in such a manner that, when quantity of rear light is smaller, the amount of coloration of the electrochromic element is smaller whereas, when the quantity of rear light is larger, the amount of coloration of the electrochromic element is larger.; The response speed control circuit (34) performs control of the response speed in such a manner that, when the quantity of rear light is smaller, the response speed of the electrochromic element in a color imparting direction is lower whereas, when the quantity of rear light is larger, the response speed of the electrochromic element in the color imparting direction is higher.
