First, second and third dopes 114, 115 and 116 each of which contains a solid electrolyte and an organic solvent are cast from a casting die 81 provided with a feed block 119 to a moving belt 82. A three-layer casting membrane 112 is peeled off from the belt 82 as a three-layer membrane 62 containing the organic solvent. After being dried in a tenter device 64, the membrane 62 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 62 is transported to a drying chamber 69 and dried while being supported by the plural rollers.
