Light transmissive element

A light transmissive element including a light transmissive area, the light transmissive element comprising:

• first and second transparent substrates disposed so as to face each other across a gap,
• first and second transparent conductive films formed on facing surfaces of the first and second substrates, respectively;
• and
• an electrolyte filled in the gap, wherein
• the electrolyte contains a metal ion and is prepared so as to allow the metal ion to be reversibly deposited on a surface of the first transparent conductive film or the second transparent conductive film via electrodeposition according to a state of applied voltage between the first transparent conductive film and the second transparent conductive film,
• in the light transmissive area, a first dividing line is formed in the first transparent conductive film,
• the first transparent conductive film includes a first-first divisional area and a first-second divisional area in the light transmissive area, the first-first divisional area and the first-second divisional area being electrically insulated from each other by the first dividing line,
• in the light transmissive area, the second transparent conductive film includes a continuous area with no dividing line,
• the light transmissive element includes a first-first metal electrode and a second metal electrode,
• the first-first metal electrode is connected to the first-first divisional area and is not connected to the first-second divisional area,
• the second metal electrode is connected to the second transparent conductive film,
• the second metal electrode includes a second-first metal electrode and a second-second metal electrode separated from each other,
• the second-first metal electrode is connected to the second transparent conductive film at a position where an area located between the first-first metal electrode and the second-first metal electrode with regard to a surface direction of the light transmissive element is present in an area facing the first-first divisional area and is not present in an area facing the first-second divisional area, and
• the second-second metal electrode is connected to the second transparent conductive film at a position where an area located between the first-first metal electrode and the second-second metal electrode with regard to the surface direction of the light transmissive element is present in an area facing both the first-first divisional area and the first-second divisional area.
