An electrical connector includes an insulating body and a plurality of signal terminals and ground terminals contained therein. Each terminal includes a contact portion, a foot portion and a connection portion therebetween. The contact portions are arranged in two lines on the insulating body, and the foot portions are arranged in two lines. The locations of the free ends of the foot portions included in one line correspond with the location arrangement of their contact portions. Compared with the free ends of the foot portions of each signal terminal pair in the line, the distance between the free ends of the foot portions of two corresponding adjacent terminals in the other line is increased.
