Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a filter to which the countermeasure of electrostatic ground is applied and which has a high dust collection capability. SOLUTION: A filter medium 10 is heated and compressed by sewing ground fibers 11 on the upper face and opposite face of the filter medium 10 by a sewing machine and pressing the heating plate to the filter medium 10 along the sown ground fibers 11. The filter medium 10 is deformed by heating and compression and is heat-set, and thereby the pine hole 12 is plugged. COPYRIGHT: (C)2006,JPO&NCIPI
