Abstract
A double-laterally-wound two-core parallel extrafine coaxial cable includes two cores, having internal conductors whose outer peripheries are covered with insulators and disposed in parallel with each other. A first laterally-wound shield is applied to the outer periphery of the two cores. A second laterally-wound shield is applied to the outer periphery of the first laterally-wound shield in a direction opposite to that of the first laterally-wound shield. A composite tape, which includes a plastic tape having a vapor-deposited metal layer formed on one surface thereof, is wound around the outer periphery of the second laterally-wound shield such that the vapor-deposited metal layer faces the second laterally-wound shield. A jacket covers the outer periphery of the composite tape. Each of the cores has a core outer diameter, and the laterally-wound shields are formed of wire having a wire diameter. The pitch of the lateral winding of the laterally wound shields is 10 to 20 times the sum of twice the core outer diameter and twice the wire diameter.
