Abstract
A liquid type electrochromio (EC) element is configured by substrates having tapping electrode portions as a part of a unified substrate by the processing of the substrate. When the upper and lower tapping electrode portions are provided on one side such that they are not piled up with each other, the ratio of the effective area can be increased and the area for covering the tapping electrode portions can be decreased in comparison with the technique in which the upper substrates are shifted with each other. Also, since the areas of the tapping electrode portion can be decreased in comparison with the technique in which the upper substrates are shifted with each other, the weight of the EC element can be decreased. Also, the weight can be decreased by dividing the tapping electrode portion into two tapping electrode portions each having such size that one is not piled up with another. Since the tapping electrode portion and the upper electrode portion are not piled up with each other when viewed from the direction of laminating the substrates, the liquid type electrochromic element can be connected via a clip electrode.
