The differential transmission cable comprises a cable having at least one pair of differential transmission lines, one or more transmission transformers, and connectors at both ends, the transmission transformer having an integrally sintered laminate structure and a coupling coefficient of 0.65 to 0.98 at 100 MHz, the distance between a center of the transmission transformer and a tip end of the closest connector being within 0.1 m, and the distance between a center of the transmission transformer and a tip end of the farthest connector or between a center of the transmission transformer and a center of the other transmission transformer being 0.5 to 4 m. The transmission transformer is mounted onto a substrate, which is inserted into the connector or a housing of the connector having lands or a positioning holder. After wiring, the connector including the substrate is integrally resin-molded.
