An electrochromic cell typically comprises two parred, transparent plates (1, 2) with a spacing between them, which are each provided on the side facing the other with an electrically conductive electrode layer (3, 4) which extends over the entire area of the plate and is in each case connected to an external electric connection, which are joined to one another so as to form a seal by means of a bead of adhesive (6) running round the edge region of the plates (1, 2) and in each case leaving a narrow margin (7a, 7b) free, and between which an electrochromic medium (5) is located.According to the invention, a laminate (8) of metal/solid nonconductor/metal layers is located around the periphery in the space between the two margins (7a, 7b).This laminate ensures firstly a predetermined spacing of the two plates forming the cell walls and, secondly, serves for making a contact with the planar electrodes (3, 4).
