Abstract
A resin containing a prescribed filler that can minimize a change in moisture content is used in an electrochromic film as a sealing resin, and further the outer circumference is sealed by a silyl-containing polymer. Here, by the use of the epoxy resin containing the prescribed filler, which can minimize a change in moisture content in an electrochromic film, the moisture content in the electrochromic layer can be stabilized to a level near the use of the sealing glass relative to the environmental changes such as a high temperature and a high humidity. Consequently, there is an extremely high possibility to avoid the use of sealing glass in comparison with the use of a conventional resin. However, to secure resistance to an elevated temperature and resistance to a high humidity on a practically satisfied level, the outer circumference is further sealed by a silyl-containing polymer.
