PROBLEM TO BE SOLVED: To provide an ion exchange filter and its production method, capable of expecting production flow creation and handling performance improvement of various products, and highly enhancement of filtering performance. SOLUTION: A communicated porous molding, obtained by heating and calcinating a synthetic fiber powder, is impregnated with a raw solution of an ion exchange resin and this raw material is block polymerized in the communicating porous molding to form the ion exchange filter. Water is preferably contained in the raw solution. An amount of water contained, which is not limited in particular, is preferably more than 0 and less than 25 mass parts and more preferably 5-15 mass parts. COPYRIGHT: (C)2006,JPO&NCIPI
