Composite cable and composite harness

A composite cable, comprising:

• a pair of first electric wires;
• a twisted pair wire formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires;
• and
• a tape member spirally wound around an assembled article that is formed by twisting the pair of first electric wires and the twisted pair wire together,
• wherein a twist direction of the twisted pair wire, a twist direction of the assembled article and a winding direction of the tape member are a same direction,
• wherein a twist pitch of the twisted pair wire is smaller than a twist pitch of the assembled article, and a winding pitch of the tape member is smaller than the twist pitch of the assembled article and is not less than the twist pitch of the twisted pair wire.
