ABSTRACT:
A shield cable, in which a winding looseness of a shield layer due to twisting can be decreased and a short-circuit between a shield layer and signal conductor as well as a disconnection of the signal conductor is prevented, and a wiring component and information apparatus having the shield cable are provided. A twisted conductor is covered with an insulator to form an insulated wire with an outer diameter of 0.3 mm or less. This insulated wire is covered with a shield conductor and a sheath so as to form a shield cable. The shield conductor consists of a plurality of shield layers. The first shield layer at an inner most part is formed by winding conductors spirally with a scroll pitch of 7 to 13 mm. One shield cable may contain two insulated wires.
