An electronic device connection cable includes a transmission part including 18 high-speed signal lines, 20 ground lines, and 22 low-speed signal lines. The electronic device connection cable further includes a tube-shaped sheath within which the transmission part is disposed such that the surface of the transmission part is covered with the sheath. The transmission part includes a first layer disposed at an outermost location, a second layer which is radially inwardly adjacent to the first layer, and a third layer which is radially inwardly adjacent to the second layer. In the first layer, 12 high-speed signal lines and 12 ground lines are alternately disposed. In the third layer, the remaining 6 high-speed signal lines and 6 ground lines are alternately disposed. In this structure, any two high-speed signal lines are not disposed at directly adjacent locations, and thus it is ensured that data can be transferred in a highly reliable fashion without being significantly influenced by noise.
