The problem to be solved by the present invention is to provide an electrochromic gel which is excellent in flexibility and which is stretchable, a method for producing the gel, a method for controlling electronic printing and erasing, and a stretchable display. The problem is solved by using an electrochromic gel obtained by laminating an electrolyte-containing gel layer consisting only of an electrolyte-containing gel and an organic-metallic hybrid polymer-containing layer obtained by containing an organic-metallic hybrid polymer in the electrolyte-containing gel.
