<P>PROBLEM TO BE SOLVED: To provide a magnetic filter keeping a magnetic field gradient drastically increased by a simple and excellent means capable of micronizing a magnetic body and having reproducibility from an aspect of production efficiency, and a magnetic separation efficiency sharply increased. <P>SOLUTION: The magnetic filter is constituted of a magnetic structure having liquid or gas transmitting flow channels. The magnetic structure is constituted by filling an opposed surface open type container with a large number of alumina particles obtained by filling pores distributed to the surface of the magnetic structure with the micronized magnetic body and the gaps between the particle are set to the transmitting flow channels. <P>COPYRIGHT: (C)2008,JPO&INPIT |
