Electrochromic apparatus, electrochromic element, and method of manufacturing electrochromic element

An electrochromic element, comprising:

• a first support;
• a first electrode layer on the first support;
• a second support;
• a second electrode layer on the second support, the second electrode layer facing the first electrode layer;
• an electrolyte layer between the first electrode layer and the second electrode layer;
• an electrochromic layer in contact with the first electrode layer;
• and
• a first auxiliary electrode in contact with the first electrode layer and embedded in the first support while forming a flat surface with the first support, the first auxiliary electrode including a material having a resistance lower than that of the first electrode layer.

A method of manufacturing an electrochromic element, comprising:

• forming a plurality of recesses on at least one of a first surface of a first support and a second surface of a second support, the first surface and the second surface facing with each other;
• forming an auxiliary electrode at each one of the recesses;
• flattening the first surface or the second surface having the auxiliary electrode on which an electrochromic layer is formed;
• and
• forming an electrolyte layer between the electrochromic layer and one of the first surface and the second surface.
