PURPOSE:To obtain an EC element which has good efficiency in working, permits continuous production, is suitable for mass production and is low in production cost by imposing a gel-like electrolyte soln. on the surface of the 1st substrate enclosed with a dam by a sealant and press-sticking the 2nd substrate onto said substrate from above under the reduced pressure to form a cell. CONSTITUTION:The surface of the 2nd substrate 7 presses first the gel-like electrolyte soln. 5 when the substrate 7 is successively pressed from above by a pressing device 9. The soln. 5 is then spread on the surface of the 1st substrate 1 and contacts with the dam 4 which is an outside frame, thus spreading further along the dam 4. The dam 4 is then pressed and compressed as the dam contacts with the surface of the 2nd substrate 7, by which the dam is press-stuck to the four circumferential sides of the substrates 2, 7 thereby forming the cell. The soln. 5 is packed into the cell formed in such a manner. The cell in such a state is held for several minutes in a vacuum vessel, by which the press sticking of the realant forming the dam 4 to both substrates 2, 7 is completed and the secure cell is obtd. The gaseous N2 is thereafter introduced into a vacuum vessel to maintain the state of 1atm therein. The cell is taken out of the vacuum vessel into the atm. The cell in which the electrolyte soln. is thoroughly packed and no foam exists is thus finished.
