Resin substrate and electronic device

A resin substrate comprising:

• an insulating substrate;
• a first signal conductor and a second signal conductor that are provided on the insulating substrate, the first signal conductor and the second signal conductor partially extending in parallel or substantially in parallel with each other along a signal transmission direction;
• a first external connection terminal that is connected to one end of the first signal conductor in the signal transmission direction and exposed at a first surface of the insulating substrate;
• and
• a second external connection terminal that is connected to one end of the second signal conductor in the signal transmission direction and exposed at the first surface of the insulating substrate;
• wherein
• the first external connection conductor and the second external connection conductor are arranged side by side along the signal transmission direction;
• the first signal conductor includes a parallel portion that extends in parallel or substantially in parallel with the second signal conductor along the signal transmission direction, and a first connection portion that connects the parallel portion and the first external connection conductor;
• in a portion where the first signal conductor and the second signal conductor extend in parallel or substantially in parallel with each other, the first signal conductor and the second signal conductor are disposed at a common position in a thickness direction of the insulating substrate;
• and
• the first connection portion is disposed at a different position from the second signal conductor in the thickness direction and a width direction of the insulating substrate.
