Abstract

A wiring board includes a first wiring layer, a high-speed wiring disposed in the first wiring layer, a second wiring layer, and a signal wiring disposed in the second wiring layer. The signal wiring transmits a signal slower than that through the high-speed wiring. A third wiring layer between the first and second wiring layers includes a power supply wiring and/or a ground wiring, which is not disposed in a portion where a land of the first wiring layer and the signal wiring do not overlap. The power supply wiring and/or the ground wiring overlap the signal wiring in a portion where the land of the first wiring layer and the signal wiring overlap each other.
