<p>The flat cables 101 and 102 are characterized in that the external diameter of the coaxial cables 10 is 0.15 to 0.35 µm, at least a portion of the outer circumference of each coaxial cable 10 is fastened to a laminated sheet 50 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 101 and 102, since a plurality of coaxial cables 10 are fastened to one or more laminated sheets 50 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.
