<P>PROBLEM TO BE SOLVED: To provide a low cost ion exchanger excellent in assembling properties. <P>SOLUTION: The ion exchanger has an ion exchange resin body, which has a laminated structure comprising sheet-like ion exchange resin layers, and an almost tubular case for housing the ion exchanger resin body. Since this ion exchanger requires no holding plate arranged heretofore in order to suppress the outflow of the ion exchange resin, it has a cost reducing effect due to reduction of the number of parts. Further, since the ion changer can be produced only by arranging the sheet-like ion exchange resin layers in a case, it can be produced at a low cost. In addition, since this ion exchanger is constituted so as to easily separate the sheet-like ion exchange resin layers, the recyclability of the sheet-like ion exchange resin layers is excellent. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
