PROBLEM TO BE SOLVED: To provide an electrochromic mirror capable of providing a clear reflected image, by preventing or effectively suppressing the occurrence of troubles, such as large degradation in the reflectivity, even if the mirror is formed into a structure with a hole formed on an electrically conductive reflecting film. SOLUTION: In this electrochromic mirror 10, the relation between the ratio of an inner diameter D of a through-hole 70 to the center-to-center distance L of the through-holes 70 adjacent to each other, and the diffuse reflectance is shown by a graph. As shown in Figure, when the ratio of the inside diameter dimension D to the center-to-center distance L is set not smaller than 7, the scatter of light caused by a diffraction phenomenon of light in a boundary of the through-holes 70 is very effectively reduced. Thereby, occurrence of optical interference by a reflection image formed by reflected light and white turbidity thereof can be prevented or effectively suppressed. COPYRIGHT: (C)2009,JPO&INPIT
