摘要： A differential transmission line connector with little unwanted radiation noise is provided. A connector connects a differential transmission pattern for multiple transmission of a group of three differential signals and a differential transmission cable. The differential transmission pattern is provided with three signal lines, and the differential transmission cable also is provided with three signal lines. In a plane that is perpendicular to the longitudinal direction of the differential transmission pattern and the differential transmission cable, the signal lines are positioned at the apexes of an equilateral triangle. The connector is provided with three signal lines that connect, at identical lengths, the signal lines of the differential transmission pattern and the signal lines of the differential transmission cable, between a predetermined first plane of the planes that perpendicularly intersect the longitudinal direction of the differential transmission pattern and a predetermined second plane of the planes that perpendicularly intersect the longitudinal direction of the differential transmission cable.
