Electronic device connection cable and electronic device

An electronic device connection cable, comprising:

• a plurality of signal lines including at least two high-speed signal lines and at least one signal line selected from the group consisting of a ground line and a low-speed signal line;
• the plurality of signal lines being disposed in a multilayer structure including at least inner layer and an outer layer, the inner layer being located adjacent to the outer layer;
• and
• the plurality of signal lines being arranged so that one high-speed signal line is not directly adjacent another high-speed signal line.

An electronic device including a main unit, a peripheral unit, and a connection cable for connecting the peripheral unit to the main unit, the connection cable comprising:

• a plurality of signal lines including at least two high-speed signal lines and at least one signal line selected from the group consisting of a ground line and a low-speed signal line;
• the plurality of signal lines being disposed in a multilayer structure including at least inner layer and an outer layer, the inner layer being located adjacent to the outer layer;
• and
• the plurality of signal lines being arranged so that one high-speed signal line is not directly adjacent another high-speed signal line.
