Abstract
A multi-core flat cable for a vehicle includes a sheath covering two power wires and at least two signal wires. A pair of the signal wires is twisted and is configured as one twisted pair of signal wires. On a section perpendicular to a longitudinal direction, a ratio (long-axis dimension/short-axis dimension) of a long-axis dimension to a short-axis dimension is equal to or greater than 1.8.

A multi-core flat cable for vehicle comprising:
- two power wires, each of which comprising a first conductor and a first insulating layer covering the first conductor;
- two signal wires, each of which comprising a second conductor thinner than the first conductor and a second insulating layer covering the second conductor;
- and
- a sheath covering the two power wires and the two signal wires,
- wherein a pair of the signal wires is twisted and is configured as one twisted pair of signal wires,
- wherein the two power wires and the twisted pair of signal wires are aligned in line,
- wherein the two power wires are disposed to be adjacent to each other and to be in contact with each other,
- wherein one of the two power wires and the twisted pair of signal wires are disposed to be adjacent to each other and to be in contact with each other, and
- wherein on a section perpendicular to a longitudinal direction, a ratio (long-axis dimension/short-axis dimension) of a long-axis dimension to a short-axis dimension is equal to or greater than 1.8.
