Abstract

Official abstract text for this publication.

Provided is an electrochromic device including an electrochromic element including a protrusion on a periphery of the electrochromic element, and a frame holding the electrochromic element, wherein the protrusion includes an electrode pad, and the frame includes a connecting member configured to electrically connect to the electrode pad.

First claim

Opening claim text (preview).

What is claimed is: 1. An electrochromic device comprising: an electrochromic element including a protrusion on a periphery of the electrochromic element; and a frame holding the electrochromic element, wherein the protrusion includes an electrode pad, the frame includes a connecting member configured to electrically connect to the electrode pad, and wherein at least one of the following conditions is met: the electrochromic element includes a first substrate, a first electrode layer, an electrochromic layer, an insulating inorganic-particle layer, a second electrode layer, and a second substrate in the order as mentioned, and an electrolyte is disposed between first electrode layer and the second electrode layer, the electrochromic element includes a first substrate, a first electrode layer, an electrochromic layer, an insulating porous layer, a second electrode layer having through holes, and a deterioration prevention layer in the order as mentioned, and an electrolyte is disposed between the first electrode layer and the deterioration prevention layer, or the connecting member is an elastic material that can press against the electrode pad. 2. The electrochromic device according to claim 1 , wherein the electrochromic element includes a first substrate, a first electrode layer, an electrochromic layer, an insulating inorganic-particle layer, a second electrode layer, and a second substrate in the order as mentioned, and an electrolyte is disposed between first electrode layer and the second electrode layer. 3. The electrochromic device according to claim 2 , wherein an edge of the first electrode layer or the second electrode layer is electrically connected to the electrode pad with a conductive adhesive. 4. The electrochromic device according to claim 2 , wherein the first substrate is a lens. 5. The electrochromic device according to claim 1 , wherein the electrochromic element includes a first substrate, a first electrode layer, an electrochromic layer, an insulating porous layer, a second electrode layer having through holes, and a deterioration prevention layer in the order as mentioned, and an electrolyte is disposed between the first electrode layer and the deterioration prevention layer. 6. The electrochromic device according to claim 1 , wherein the connecting member is an elastic material that can press against the electrode pad. 7. The electrochromic device according to claim 6 , wherein the elastic material is a flat spring. 8. The electrochromic device according to claim 1 , wherein the electrode pad is a metal foil. 9. The electrochromic device according to claim 1 , wherein the electrochromic element is in the shape of a lens. 10.
