[PROBLEMS] To arrange large diameter wires with no interference between them and to reduce crosstalk sharply in a differential transmission connector and a differential transmission connector for fixing a substrate. [MEANS FOR SOLVING PROBLEMS] The differential transmission connector comprises a plurality of pairs of differential transmission contacts (16a, 16b) held on an insulating housing, and ground contacts (16c) corresponding to respective pairs. The differential transmission contacts (16a, 16b) and the ground contacts (16c) are arranged in two rows at a fitting portion and a wire joint. At the fitting portion, first contacts (16a) constituting one of the pair of differential transmission contacts (16a, 16b) are arranged in a first row, second contacts (16b) constituting the other of the pair of differential transmission contacts are arranged in a second row, and the ground contacts (16c) are arranged between closest differential transmission contacts (16) in each row. |
