FULLY SOLID ELECTROCHROMIC ELEMENT

As shown in Fig. 3, in the present invention, a tapping electrode 2a for a lower electrode film 2 and a tapping electrode 4a for an upper electrode film 4 are provided on one side of an area around a substrate 1. By placing the electrode-tapping elements on one side, for example, applying the electrochromic element to an automobile antiglare mirror, the effective field of the mirror is increased to contribute the safety. a mirror ring which surrounds the outer circumference of the mirror can be made slim, enhancing a smart looking from the viewpoint of the design. Also, in comparison with the case where the electrode is tapped on two or more sides, the present invention makes it possible to secure the same effective visibility with a lightweight.
