Abstract
The present disclosure provides an EC element in which a separator divides the gap between a pair of electrodes into two sections defining a pair of EC layers, each containing an EC compound. The separator has a smaller thermal expansion coefficient than the electrodes and is bonded to each of the electrodes with an acrylic adhesive. The acrylic adhesive enables the separator to be provided without wrinkles or sagging.

An electrochromic element comprising:
- a first electrode;
- a second electrode;
- a separator that divides a gap between the first electrode and the second electrode into two sections;
- a first electrochromic layer disposed between the first electrode and the separator and containing at least one electrochromic compound;
- and
- a second electrochromic layer disposed between the second electrode and the separator and containing at least one electrochromic compound,
- wherein the separator has a smaller thermal expansion coefficient than the first and second electrodes, and each of the first electrode and the second electrode is bonded to the separator with an acrylic adhesive.
A method for manufacturing an electrochromic element including a first electrode, a second electrode, a separator that divides a gap between the first electrode and the second electrode into two sections, a first electrochromic layer disposed between the first electrode and the separator and containing at least one electrochromic compound, and a second electrochromic layer disposed between the second electrode and the separator and containing at least one electrochromic compound, the method comprising:
- bonding each of the first electrode and the second electrode to the separator with an acrylic adhesive, curing the acrylic adhesive, and then heat-treating the acrylic adhesive.
