うになる。 In FIGS. 1 and 2, reference numeral 1 denotes a reflecting mirror main body having a substantially rectangular plate shape as a whole, and is roughly constructed as described below. That is, 2 is a rectangular transparent substrate made of glass, for example, and 3 is this transparent substrate 2.
A transparent electrode attached on top, for example In 2 O 3
and SnO 2 as an ITO film.
Reference numeral 4 denotes a first coloring layer that is attached in the form of a film on the transparent electrode 3 by vapor deposition means, and is made of a reversibly electroreducible electrochromic material (for example, WO 3 ). Reference numeral 5 denotes an intermediate layer made of a dielectric material (for example, SiO 2 ) attached in the form of a film on the first coloring layer 4 by vapor deposition means. Reference numeral 6 denotes a second coloring layer which is attached in the form of a film on the intermediate layer 5 by vapor deposition means, and is made of a reversibly electrolytically oxidizable electrochromic material (for example, NiO). 7 is a layer of Al, for example, which is attached in the form of a film on the second coloring layer 6 by vapor deposition means.
The front surface (lower surface in FIG. 2) of the mirror electrode constitutes a light reflecting surface 7a. The transparent electrode 3, first color-forming layer 4, intermediate layer 5, second color-forming layer 6, and mirror electrode 7 described above constitute an all-solid-state electrochromic device 8. Further, in this case, the electrochromic element 8
In this case, the first color-forming layer 4 is located in the portion indicated by A in FIG.
The intermediate layer 5, the second coloring layer 6, and the specular electrode 7 are removed, and the portion indicated by B in FIG. The structure is such that the transparent electrode 3 of the part) is removed. In other words, as a result of this configuration, the portion where at least one of the pair of transparent electrodes 3 and the mirror electrode 7 is removed from the peripheral edge of the reflecting mirror body 1 extends over the entire circumference of the reflecting mirror body 1. It is set up like this. Therefore, in such an electrochromic device 8, when a DC voltage is applied between the transparent electrode 3 and the mirror electrode 7 with the mirror electrode 7 side having a positive potential, the water in the intermediate layer 5 becomes hydrogen ions (H + ). and hydroxyl ion (OH - ),
Hydrogen ions (H + ) move to the negative potential transparent electrode 3 and eventually to the first coloring layer 4 and are reduced, while hydroxide ions (OH - ) move to the positive potential mirror electrode 7 and eventually the second coloring layer. It moves to the layer 6 side and is oxidized. Therefore, the first and second coloring layers 4 and 6 are colored (colored) by such reduction and oxidation reactions, and as a result of such coloring, the light transmittance of each coloring layer 4 and 6 increases. As a result, the reflected image on the light reflecting surface 7a becomes darker (in other words, the overall light reflectance decreases), and an anti-glare effect can be obtained.

Since at least one of the pair of transparent electrodes 3 and mirror electrodes 7 of the electrochromic element 8 located at the sandwiched portion by the holder 9 is removed, the electrochromic element 8 is located at the sandwiched portion. Even if the electrochromic element 8 is damaged, there is no risk of a shot accident occurring between the two electrodes 3 and 7 as in the conventional case, and therefore, there is no possibility that the performance of the electrochromic element 8 will deteriorate and the life span thereof will be shortened due to this. be.
