Abstract

PURPOSE:To provide a method for manufacturing a filter element whose surface does not foul and which excels in mass productivity. CONSTITUTION:A filter element having continuously plural casing bodies 6 which a corrugated filter medium 99 and a flat filter medium 91 are welded together to form is manufactured. The corrugated filter medium 99 is arranged on the corrugated surface 20 side of a corrugated weld roller 2, while the flat filter medium 91 is arranged on the ultrasonic welding machine 1 side. And both filter media 91, 99 are put one over the other and passed on by the rotation of the corrugated weld roller 2 and simultaneously the flat filter medium 91 and a lower part 991 of the corrugated filter medium 99 are welded by the ultrasonic vibration of the ultrasonic welding machine 1. And by 1 narrowing the clearance between the ultrasonic welding machine 1 and the corrugated surface 20, an independent filter element 9 is manufactured.
