A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A differential signal transmission cable includes a conductor, a first dielectric covering the conductor, an outer conductor covering the first dielectric, a second dielectric covering the outer conductor and including a material with a higher transmission loss than the first dielectric, and a shield covering the second dielectric. A multi-core differential signal transmission cable includes a plurality of wires each including a conductor, a first dielectric covering the conductor and an outer conductor covering the first dielectric, a second dielectric covering all the plurality of wires and including a material with a higher transmission loss than the first dielectric, and a shield covering the second dielectric.

A cable (2100) includes one or more conductor sets, one or more dielectric unitary blocks (2102) or reservoirs, first and second conductive shielding films (2108) disposed on opposite first and second sides of the conductor sets and the dielectric blocks (2102) or reservoirs, and an adhesive layer (2140). The shielding films (2108) include cover portions and pinched portions arranged such that, in cross-section, the cover portions of the shielding films in combination substantially surround each conductor set and each unitary block (2102) or reservoir, and the pinched portions of the shielding films in combination form pinched portions of the cable on each side of the conductor set and on at least one side of the unitary block (2102) or the reservoir. The adhesive layer (2140) bonds the first shielding film to the second shielding film in the pinched portions of the cable.

A coaxial cable includes a coaxial wire in which an inner insulator, an outer conductor and a sheath are sequentially and coaxially provided around a center conductor, and a substrate having a surface on which a first contact pad and a second contact pad are arranged. The sheath is removed at one end portion of the coaxial wire by a predetermined length, so that the inner insulator and the outer conductor are exposed, and a tip end of the inner insulator is removed by a predetermined length, so that the center conductor is exposed. The exposed portion of the center conductor is soldered to the first contact pad with the exposed portion of the inner insulator being bent relative to the sheath, and the exposed portion of the outer conductor is soldered to the second contact pad with being bent in a direction different from the bending direction of the inner insulator. A part of the coaxial wire covered by the sheath is standing at an angle of 30° or greater relative to the surface of the substrate.
