Abstract: A flat cable in which at least end portions of a plurality of coaxial cables are securely arranged in parallel on a sheet is characterized in that a flat cable edge-machined portion for electric connection of the coaxial cables is formed at the end portion of the plurality of coaxial cables, and a part of the sheet is made to remain in a band shape across an entire width of the flat cable between a machined edge portion of the edge-machined portion and a distal end of the flat cable, and a jacket of the coaxial cable is secured to the band-shaped sheet.

Abstract: A flat cable of the invention in which at least end portions of a plurality of coaxial cables are securely arranged in parallel on a sheet is characterized in that the sheet is made to remain in a band shape across an entire width of the flat cable, at a middle portion of a flat cable edge-machined portion for electric connection of the coaxial cables. Accordingly, a plurality of coaxial cables exposed at an end portion of the flat cable by the cable end process have their middle portions, fixed to the sheet, made to remain in a band shape. This makes it difficult for the coaxial cables to be separated part at the end portion of the flat cable, and making it possible to well keep the pitch accuracy among the coaxial cables and easily and surely achieve complex and troublesome electric connection.

Abstract: Flat cables having an external diameter of coaxial cables of 0.15 to 0.35 ?m, at least a portion of the outer circumference of each coaxial cable fastened to a laminated sheet composed of a porous polytetrafluoroethylene. The flat cables are constructed so that these flat cables can pass via a through-hole with an internal diameter of 2.0 to 5.5 mm.

Abstract: Flat cables are characterized in that the external diameter of the coaxial cables is 0.15 to 0.35 ?m, at least a portion of the outer circumference of each coaxial cable is fastened to a laminated sheet composed of a porous polytetrafluoroethylene (EPTFE), and the flat cables are constructed so that these flat cables can pass via a through-hole with an internal diameter of 2.0 to 5.5 mm. As a result, in the flat cables and since a plurality of coaxial cables are fastened to one or more laminated sheets composed of EPTFE, these flat cables are superior in terms of softness and flexibility and can be passed through even an extremely small through-hole while maintaining the precision of the pitch between the coaxial cables at a favorable level, by folding or rolling up the flat cables in the direction of length.
