1. A composite cable comprising:
a plurality of first electric wires each having a first conductor and a first resin layer covering the first conductor;
an internal cable including a plurality of second electric wires each having a second conductor and a second resin layer covering the second conductor, a first sheath formed of a resin material covering a periphery of the plurality of second electric wires and being interposed between the plurality of second electric wires, a shield covering a periphery of the first sheath and contacting the first sheath, and a second sheath covering a periphery of the shield and contacting the shield; and
a covering member that covers peripheries of the plurality of first electric wires and the internal cable,
wherein the covering member forms an outermost peripheral surface of the composite cable,
wherein the first sheath is provided with irregularities which enhance surface roughness of an outer peripheral surface of the first sheath contacting the shield, and
wherein the second sheath is provided with irregularities which enhance surface roughness of an outer peripheral surface of the second sheath contacting the first electric wires and the covering member.
