To provide a differential signal transmission connector and a board mountable differential signal transmission connector in which large diameter wires can be arranged without interference, and crosstalk is greatly reduced. A differential signal transmission connector is equipped with: a plurality of differential signal transmission contact pairs (16a, 16b), which are held in an insulative housing; and grounding contacts (16c) corresponding to each of the differential signal transmission contact pairs. The differential signal transmission contact pairs (16a, 16b) and the grounding contacts (16c) are arranged in two rows at an engaging portion and at a wire connecting portion. First contacts (16a) from among the differential signal transmission contact pairs (16a, 16b) are arranged in a first row at the engaging portion. Second contacts (16b) from among the differential signal transmission contact pairs (16a, 16b) are arranged in a second row at the engaging portion. The grounding contacts (16c) are arranged between the closest differential signal transmission contacts (16a, 16b) within the first row and the second row at the engaging portion. |
