Abstract
In this circuit board, first signal wiring portionsand second ground wiring portionsof a first wiring layerare adjacent to each other in a pitch direction. Further, second signal wiring portionsand first ground wiring portionsof a second wiring layerare adjacent to each other in the pitch direction. In the pitch direction, outer edgesof line portionsof two first signal wiring portionsare located more inward than both edgesof a line portionof the first ground wiring portions. Outer edgesof line portionsof two second wiring portionsare located more inward than both edgesof the line portionof the second ground wiring portion. This achieves good signal transmission characteristics without providing a ground layer separate from a signal layer.
