Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a wiring board for differential signal transmission, which inexpensively provides a large-sized substrate, wherein the characteristics of different-width BCS pair wires that include a GND plane vary less. SOLUTION: The wiring board for differential signal transmission includes pair wires for differential signals which comprise a first wire 11 and a second wire 12 which are laminated and disposed; furthermore, layers (20, 21, and 22), and the wire width of the first wire 11 of the pair wires for differential signals is wider than that of the second wires 12; and the second wire 12 is within the first wire 11 when viewed from above in a lamination direction.
