Abstract
First, second and third dopes each of which contains a solid electrolyte and an organic solvent are cast from a casting die provided with a feed block to a moving belt. A three-layer casting membrane is peeled off from the belt as a three-layer membrane containing the organic solvent. After being dried in a tenter device, the membrane still containing the organic solvent is contacted with a liquid which is a poor solvent of the solid electrolyte and having lower boiling point than the organic solvent. Thereafter, the membrane is transported to a drying chamber and dried while being supported by the plural rollers.
