Abstract: Electrochromic mirrors have, as a central component, an optically active cell which comprises two plates (1, 2) which are arranged in a laminate-like fashion and which are provided in each case on the inside with a planar electrode between which an electrochromic medium (5) is located and which are connected to one another in a sealed fashion by means of a bead (6) of adhesive which runs around the edge region of the plates (1, 2) and leaves a narrow edge strip exposed. In order to ensure a secure attachment of connecting wires (8a, 8b) which does not change the dimensions of the mirror, each edge strip of the planar electrodes is divided in half into an insulated edge-strip section (11a, 11b) by means of a separating trench (9a, 9b) such that in each case the insulated edge section lies opposite with the non-insulated edge section of the other surface electrode.
