<p><P>PROBLEM TO BE SOLVED: To provide a gas removing filter having high gas permeability and adsorbing collection performance of gaseous impurity components, and a very long service life, without polluting a using environment. <P>SOLUTION: In this gas removing filter of the present invention, a base material 1 has end faces 5a, 5b, fibers 2 are connected to the end faces 5a, 5b and three-dimensionally installed close together in one direction. The base material 1 has structure formed by integration of the fiber group three-dimensionally installed close together in one direction. As the base material 1 consisting of the fiber group three-dimensionally installed close together in one direction has adsorption capacity, the gas removing filter with a long service life and high gas permeability can be provided. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
