Electrochromic sheet, lens for eyeglasses, and eyeglasses

An electrochromic sheet comprising:

• a first substrate;
• a second substrate which is disposed to face the first substrate;
• a sealing portion which is disposed between the first substrate and the second substrate and defines a colored region exhibiting coloration by application of a voltage;
• an electrochromic element which is disposed in the colored region;
• and
• on an outer side of the sealing portion with respect to the electrochromic element, a first conductive portion which is provided to fill a first hole portion formed from the first substrate side toward the second substrate side, and a second conductive portion which is provided to fill a second hole portion formed from the second substrate side toward the first substrate side,
• wherein the electrochromic element includes
• a first electrode and a first electrochromic layer, which are sequentially laminated on the first substrate toward the second substrate side,
• a second electrode and a second electrochromic layer, which are sequentially laminated on the second substrate toward the first substrate side, and
• an electrolyte layer which is filled between the first electrochromic layer and the second electrochromic layer,
• wherein the first electrochromic layer contains, as a main material, a material exhibiting coloration by an oxidation reaction,
• wherein the second electrochromic layer contains, as a main material, a material exhibiting coloration by a reduction reaction,
• wherein the first electrode is provided between the first substrate and the sealing portion to the first conductive portion with a patterning that, in a plan view of the electrochromic sheet, the first electrode extends from the colored region and reaches to the first conductive portion to be electrically connected to the first conductive portion,
• wherein the second electrode is provided between the second substrate and the sealing portion to the second conductive portion with a patterning that, in the plan view of the electrochromic sheet, the second electrode extends from the colored region and reaches to the second conductive portion to be electrically connected to the second conductive portion, and
• wherein the first conductive portion and the second conductive portion are each exposed at different positions at edge parts along a thickness direction of the electrochromic sheet.
