1. An electrochromic device, comprising:
- an insulating substrate;
first and second electrodes installed on said substrate at a given distance apart;
an electrochromic layer; and
an electrolyte layer, wherein said electrochromic layer is installed on said substrate not in contact with said first electrode but in contact with said second electrode, wherein said electrolyte layer is installed on said substrate in contact with said first electrode, and wherein the boundary between said electrochromic layer and said electrolyte layer lies on said substrate.

Abstract
This invention provides an electrochromic device which has superior coloration repeat properties, high light transmittance and small thickness. A film is provided comprising a first electrode and second electrode in the same plane, and an electrochromic region and electrolyte region laminated in this plane. The electrochromic region is provided on the second electrode, the electrolyte region is provided on the first electrode, and the boundary between the electrochromic region and electrolyte region lies in the planar direction of the film.
