A combination cable for a vehicle, the combination cable comprising:
- a wire bundle;
- a sheath covering the wire bundle;
- and
- an interposed layer disposed between the sheath and the wire bundle,
- wherein the wire bundle comprises a two-core first twisted pair wire, a two-core second twisted pair wire, a one-core first wire, and a one-core second wire,
- the first twisted pair wire, the second twisted pair wire, the first wire, and the second wire are twisted together in a bundled state and are arranged in a circumferential direction of the sheath in an order of the first wire, the first twisted pair wire, the second wire, and the second twisted pair wire, and
- the interposed layer includes a material that is a polyolefin resin,
- each of the first wire and the second wire includes a single insulated wire,
- each of the first twisted pair wire and the second twisted pair wire includes two insulated wires, which are twisted together,
- each of the single insulated wire and the two insulated wires includes a conductor, and a single layer insulator covering the conductor,
- the interposed layer includes a material that is paper,
- a sum of diameters of the two conductors provided in the first twisted pair wire is smaller than a diameter of the conductor provided in the first wire and is smaller than a diameter of the conductor provided in the second wire,
- a sum of diameters of the two conductors provided in the second twisted pair wire is smaller than the diameter of the conductor provided in the first wire and is smaller than the diameter of the conductor provided in the second wire,
- a material of the conductor provided in the first wire and a material of the conductor provided in the second wire are different from a material of the two conductors provided in the first twisted pair wire and a material of the two conductors provided in the second twisted pair wire,
- at least in a portion of the first twisted pair wire and the second twisted pair wire in a longitudinal direction, the first twisted pair wire and the second twisted pair wire are separated from each other,
- wherein the combination cable further comprises:
- a cross-sectional surface satisfying a first condition, a second condition, and a third condition, wherein
- in the first condition, when a straight line connecting centers of the two insulated wires provided in the first twisted pair wire is a first straight line and a straight line connecting centers of the two insulated wires provided in the second twisted pair wire is a second straight line, both the first straight line and the second straight line extend in a direction intersecting with a center line connecting a center of the first wire and a center of the second wire,
- in the second condition, when an angle formed by the first straight line and the center line is a first angle, and an angle formed by the second straight line and the center line is a second angle, the first angle and the second angle are different, and
- in the third condition, of the first angle and the second angle, one of the first and second angles is closer to being a right angle compared to the other one of the first and second angles.
