Patent attributes
A differential signal transmission cable includes a pair of insulated electric wires disposed to be parallel with each other, and a shield layer formed of a metal foil composite tape spirally wound around the pair of insulated electric wires collectively. The shield layer is formed by folding the metal foil composite tape along a longitudinal direction of the metal foil composite tape such that a surface on which a metal foil is provided is located outside to provide a folded portion, and winding the metal foil composite tape around the pair of insulated electric wires such that at least a part of the folded portion is located at a spiral overlapped region of the metal foil composite tape.
