PROBLEM TO BE SOLVED: To provide a new method for forming a BUS electrode compensating low conductivity of a transparent electrode as a single paste film using silver. SOLUTION: Silver paste 17 formed by mixing black powder 17a and white powder 17b which have different specific gravities in the paste shape is coated on transparent electrodes 6, and they are separated by their specific gravities, dried, and baked. The while powder 17b contains silver powder, and the black powder 17a comprises Cr and glass powder. The specific gravity of the black powder 17a is higher than 7, and the specific gravity of the white powder 17b is lower than 3. Since paste coating is required once, the processes are simplified and the electrodes are thinned. |
