Claim 6:
7. A circuit board, comprising:
an insulating layer;
a first via and a second via each passing through the insulating layer;
at least one first upper wiring pattern and at least one first lower wiring pattern, connected to the first via; and
at least one second upper wiring pattern and at least one second lower wiring pattern, connected to the second via, wherein:
the at least one first upper wiring pattern and at least one second upper wiring pattern are alternately disposed on an upper surface of the insulating layer,
the at least one first lower wiring pattern is disposed on a lower surface of the insulating layer to overlap the at least one second upper wiring pattern in a vertical direction, and
the at least one second lower wiring pattern is disposed on the lower surface of the insulating layer to overlap the at least one first upper wiring pattern in the vertical direction,
wherein a line width of the at least one first upper wiring pattern is different from a line width of the at least one second lower wiring pattern, and
wherein a line width of the at least one second upper wiring pattern is different from a line width of the at least one first lower wiring pattern.
