Abstract:
1. A printed circuit board having a strip line, comprising: a first insulation layer, a signal line being buried in one surface of the first insulation layer; a plurality of conductors penetrating through the first insulation layer and being disposed on both sides of the signal line in parallel with the signal line; a ground layer formed on the other surface of the insulation layer such that the ground layer is electrically connected to the plurality of conductors; a second insulation layer formed on the one surface of the first insulation layer such that the second insulation layer covers the signal line; and a power layer formed on the second insulation layer, wherein: the width of the signal line becomes narrower as the signal line extends toward the other surface of the first insulation layer, the width of each of the plurality of conductors becomes narrower as the plurality of conductors extend toward the one surface of the first insulation layer, and the signal line having sides thereof that face a corresponding side of each of the plurality of conductors in parallel.
