<P>PROBLEM TO BE SOLVED: To provide a manufacturing method of an ion exchange membrane capable of having both high ion conductivity and impermeability of liquid fuel reconciled and is suitable for a diaphragm for fuel cell. <P>SOLUTION: This is a manufacturing method of an ion exchange membrane for removing the solvent after a solvent solution of an ion exchange resin is flowed and extended on a support body. After the solvent solution of the ion exchange resin having a solvent solution viscosity of 100-3,000 poise at a temperature of 30°C is flowed, the flowed object is applied initial drying for one minute or more at a temperature of 150°C and a part of the solvent is removed from the flowed object, and further, dried at a temperature of 250°C or less. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
