Composite cable and composite harness
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.
