摘要：
A differential signal transmission cable includes two core wires, and a foamed insulation that collectively covers the two core wires by foaming extrusion molding. The foamed insulation is not more than 5% in a dispersion of foaming degree defined below in a cut surface when the cable is cut orthogonally to a longitudinal direction of the cable. In the cut surface, five regions are determined according to a predetermined procedures and a foaming degree (%) of the respective regions is measured. The dispersion of the foaming degree is defined by a difference between a foaming degree (%) in the region with a maximum foaming degree and a foaming degree (%) in the region with a minimum foaming degree.

差动信号传输电缆包括两根芯线，以及通过发泡挤出成型共同覆盖两条芯线的发泡绝缘体。 当电缆与电缆的纵向方向正交地切割时，在切割面中以下定义的发泡度的分散体中，发泡绝缘体不超过5％。 在切割面中，按照规定的程序求出5个区域，测定各区域的发泡度（％）。 发泡度的分散度由具有最小发泡度的区域中具有最大发泡度的区域的发泡度（％）和发泡度（％）之间的差定义。
