A differential signal cable is composed of two inner conductors, an insulator, which covers the two inner conductors separately or together, and an outer conductor, which covers a circumference of the insulator. When measured in a cable length of 1 m, an effective capacitance difference &Dgr;X represented by Formula (1) below is not greater than 0.2 percent of an average value C of capacitances of the two inner conductors, &Dgr;X=&Dgr;C+&Dgr;L/Z02  (1), where &Dgr;C is a difference in capacitance between the two inner conductors, &Dgr;L is a difference in inductance between the two inner conductors, and Z0 is a reference impedance (50 ohms). |
