An electrical conductor comprises three or more solid segments of identical shape. In cross-section, each segment comprises two sides, which are configured for flush bearing against correspondingly opposing lateral surfaces on another segment. The cross-sectional surface through all the constituent segments of the electrical conductor is describable by a closed curve having a stepless characteristic. All the constituent segments of the electrical conductor are stranded in combination.

Embodiments of an optical fiber cable are provided. The optical fiber cable includes at least one optical fiber, a buffer tube surrounding the at least one optical fiber, and at least one tensile element wound around the buffer tube. The at least one tensile element has a laylength of at least 200 mm. The optical fiber cable also includes an exterior jacket surrounding the tensile element. The exterior jacket is made up of at least one polyolefin, at least one thermoplastic elastomer, and at least one high aspect ratio inorganic filler. Further, the exterior jacket has an averaged coefficient of thermal expansion of no more than 120(10.sup.6) m/mK.

To provide an elastic wiring member that is to be used in connection with an electronic component or an external electronic device and that is less likely to undergo a change in resistance when the member is stretched. An elastic wiring member includes a stretchable wiring line having stretchability and connected to a contact of an electronic device main body A and a contact of an electronic component, and a base sheet, formed of a rubber-like elastic body, holding the stretchable wiring line. The elastic wiring member 11 further includes reinforcing members arranged in or on the base sheet. The reinforcing members are located adjacent to connection parts of the stretchable wiring line connected to the contacts and when the base sheet is viewed from above. The reinforcing members inhibit the base sheet from stretching and prevent deformation of the connection parts of the stretchable wiring line.
