PURPOSE:To obtain an inexpensive noise filter by rolling up three strip conductors in the tubular form through a strip insulator so as to form a coil having a distributed capacitance. CONSTITUTION:The three strip conductors 8, 11, 14 to the vicinity of both ends of which a couple of leads 9, 10, 12, 13, 15, 16 are connected are overlapped via an insulation sheet 17 respectively, they are rolled up in the tubular form so as to form a coil having a distributed capacitance. Thus, three static capacitors are formed among the three strip conductors 8, 11 and 14 in this element, and sine the three strip conductors 8, 11, 14 are coupled inductively, this element is utilized as the noise filter of various modes by using one or two of the three strip conductors as live conductors and the other as ground conductors, and since the constitution is simple, the element is manufactured inexpensively. |
