<p><P>PROBLEM TO BE SOLVED: To provide a method for easily manufacturing a filter usable for a long period of time with a small pressure loss as a gas adsorbing filter for use in a semiconductor producing device, etc. <P>SOLUTION: Activated carbon particles 1 and particle-shaped thermoplastic resins 3 are mixed together, charged into a frame 8 and heated at a temperature melting thermoplastic resins to thereby melt the thermoplastic resins. A needle-standing mold 12 where needles 11 stands is heated at the same temperature as above. After the heated material is stabbed with the needles 11, and through-holes are made, the needles 11 are pulled out. Thus, the adsorbing filter is obtained by removing the frame 8. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
