Abstract: A composite cable includes a plurality of power lines, one signal line unit, and a sheath collectively covering the plurality of power lines and the one signal line unit. The signal line unit includes a plurality of pairs of signal lines, and an inner sheath covering a first assembled article. The first assembled article is formed by arranging the signal lines to be paired at each pair of opposing vertices of a polygon with an even number of vertices in a cross-section perpendicular to a longitudinal direction of the signal line unit and twisting all the signal lines together.

Abstract: Both deformation of a cross-sectional shape of the entire composite cable and deformation of a cross-sectional shape of an electric wire included in the composite cable are suppressed. The composite cable includes: a plurality of first electric wires; a shield electric wire in which a shield layer 33 is formed around a twist pair wire 32 obtained by intertwining a plurality of second electric wires; a sheath formed around an electric wire assembly obtained by intertwining the first electric wires and the shield electric wire; a first line filler filled between the twist pair wire and the shield layer; and a second line filler filled between the electric wire assembly and the sheath. The first electric wires and the shield electric wire are intertwined in a first direction, and the second electric wires are also intertwined in the first direction.
