<P>PROBLEM TO BE SOLVED: To provide an ion exchanger capable of uniformalizing a rate of use of an inner face of an ion exchange resin plate. <P>SOLUTION: The ion exchanger 36 removing impurities in gas includes a casing 50 equipped with a gas inflow port 50b and a gas outflow port 50d forming a gas flow channel inside, and an ion exchange resin plate 60 arranged inside the casing 50 with its plate face facing toward a direction of the gas flow channel for passing gas to remove impurities. The ion exchange resin plate 60 is formed so that a resin density at a part relatively far from the gas outflow port 50d is lower. The ion exchange resin plate 60 is divided into a plurality of regions 60a to 60j, with regions relatively far from the gas outflow port 50d formed of resin with less density. <P>COPYRIGHT: (C)2009,JPO&INPIT |
