Multi-core cable for vehicle

A multi-core cable for vehicle comprising:

• two power wires each of which comprises a first conductor and a first insulating layer covering the first conductor;
• two signal wires each of which comprises a second conductor thinner than the first conductor and a second insulating layer covering the second conductor;
• two electric wires each of which comprises a third conductor thinner than the first conductor and a third insulating layer covering the third conductor;
• and
• a sheath covering the two power wires, the two signal wires and the two electric wires,
• wherein the two power wires have a same size and are made of a same material,
• wherein the two signal wires have a same size and are made of a same material, and a pair of the signal wires is twisted and is configured as a twisted pair of signal wires,
• wherein the two electric wires have a same size and are made of a same material, and a pair of the electric wires is twisted and is configured as a twisted pair of electric wires,
• wherein the two power wires, the twisted pair of signal wires and the twisted pair of electric wires are stranded,
• wherein the two power wires are disposed with a gap therebetween, and the gap is filled with fiber, and
• wherein the twisted pair of electric wires is twisted in a same direction as the twisted pair of signal wires.
