Claim Text:
1. A conductor pattern of a common-mode filter comprising a magnetic substrate, a coil layer on the magnetic substrate, and a top magnetic material formed an a top of the coil layer, wherein the common-mode filter is electrically isolated by being covered with an insulating layer of the coil layer, the conductor pattern comprising: a primary conductor pattern having both a first horizontal portion and a first vertical portion, which is vertically connected to the first horizontal portion; and a secondary conductor pattern having both a second horizontal portion and a second vertical portion, which is vertically connected to the second horizontal portion, wherein the primary conductor pattern and the secondary conductor pattern are arranged to face opposedly to one another, wherein the secondary conductor pattern is formed on the primary conductor pattern to correspond to the primary conductor pattern, wherein a horizontal width of the first horizontal portion is 10 to 15 μm, a vertical width of the first horizontal portion is 3 to 5 μm, a horizontal width of the first vertical portion is 3 to 5 μm, and a vertical width of the first vertical portion is 12 to 15 μm, and the second horizontal portion and the second vertical portion are formed with the same size as the first horizontal portion and the first vertical portion.
