摘要

Disclosed is a method for producing an electrochromic device in which to provide in the end surface of the cell an opening having a passage formed by a butyl rubber and extending not perpendicular to the end surface, to injecting an electrolyte through the opening, to seal or closing the opening by pressing deformably the outer peripheral wall of the passage so as to abut against the inner peripheral wall and to seal secondarily the sealed portion with an adhesive.
