<p>PROBLEM TO BE SOLVED: To provide a filter body having adsorptivity of active charcoal, excellent in collecting performance of particles such as floating matter in water, capable of being handled easily, and capable of being used for more longer period.SOLUTION: A filter body 10A has a hollow cylindrical shaped filter medium part 11a including active charcoal material including powder state active charcoal and fiber state active charcoal and a binder, and being formed of same composition. The filter medium part is divided in its thickness direction T for dividing it into an inflow filter medium part Di which is an inflow side of a fluid F to be filtered, and an outflow filter medium part Do which is an outflow side of the fluid F to be filtered, in which hardness of the outflow filter medium part is higher than that of the inflow filter medium part.</p> |
