Abstract: PURPOSE:To decrease a required UV exposure and to improve color developing density by having a 1st color developing process by light inclusive of wavelength light of the intrinsic absorption wavelength end of a transition metal oxide and a 2nd color developing process by the reducing current of a color developing layer. CONSTITUTION:The photoirradiated parts of an optical electrochemical element are slightly developed in colors and the absorption is generated in a visible light area by the 1st color developing process by the light inclusive of the wavelength light of the intrinsic absorption wavelength end of at least the transition metal oxide. Since the oxidation reduction potential and resistance value of the color developed parts change, the more reducing current flows from the higher potential than in the unirradiated parts flows in the photoirradiated parts and further, these parts darkly develop colors. The required UV exposure is decreased in this way and the color developing density is increased.
