PROBLEM TO BE SOLVED: To suppress crosstalk between adjacent signal lines.SOLUTION: A wiring board comprises: a substrate; a first wiring structure that is arranged above the substrate, that includes a first signal line, a second signal line, and a first ground line arranged sequentially and adjacently, and in which a distance between the first signal line and the second signal line is smaller than that between the second signal line and the first ground line; and a second wiring structure that is arranged above the first wiring structure, that includes a second ground line, a third signal line, and a fourth signal line arranged sequentially and adjacently, and in which a distance between the third signal line and the fourth signal line is smaller than that between the second ground line and the third signal line. A distance between the second signal line and the third signal line is larger than that between the second signal line and the second ground line and that between the first ground line and the third signal line.SELECTED DRAWING: Figure 3 |
