PROBLEM TO BE SOLVED: To provide a wiring board transmitting a high frequency signal to paired transmission lines extremely efficiently. SOLUTION: The wiring board has the paired transmission lines including first and second connection pads 2a, 2b disposed apart from each other at a first interval W1, first and second belt-like wiring conductors 3a, 3b having one-end sides nearby the first and second connection pads 2a, 2b and extending in parallel with each other at a second constant interval W2 narrower than the first interval W1, a first connection conductor 4a connecting the first connection pad 2a and first belt-like wiring conductor 3a to each other, and a second connection conductor 4b connecting the second connection pad 2b and second belt-like wiring conductor 3b to each other, the high frequency signal being transmitted through the paired transmission lines. The first connection conductor 4a and second connection conductor 4b are made different in inductance from each other, so that frequency characteristics of the paired transmission lines have a resonance point in the frequency band of the high frequency signal.
