<P>PROBLEM TO BE SOLVED: To provide an ion exchange filter scarcely allowing an ion exchange resin powder to fall from a filter medium and having a high ion removal efficiency of the ion exchange resin powder, and a production method for the ion exchange filter. <P>SOLUTION: The ion exchange filter 1 is made by bonding the ion exchange resin powder 4b on the filter medium by a binder 4c. Intermittent clearances 4e are formed on an adhesion surface 4d between the ion exchange resin powder 4b and the binder 4c by evaporating organic solvents 12, 13 absorbed in both the ion exchange resin powder and the binder, contracting both the ion exchange resin powder 4b and the binder 4c and peeling off part of the binder 4c from the ion exchange resin powder 4b. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
