| 摘要 |
The present invention provides an LC noise filter consisting of a capacitance and an inductance, including a first insulation sheet (20) having a plurality of portions (22-1 ... 22-8) folded alternately in the opposite directions and stacked one above another; a first conductor (40) applied to the insulation sheet at one side (20a) and adapted to form a coil having a given number of turns when the folded portions of the insulation sheet are folded alternately in the opposite directions and stacked one above another; and a second conductor applied to the insulation sheet at the other side (20b) and located substantially opposite to the first conductor to form a capacitance therebetween, whereby the filter can eliminate incoming noises without creation of any undesirable phenomenon such as ringing or the like.
