An electrical connector includes a substrate and multiple terminals. The substrate is provided with multiple accommodating holes running through the substrate vertically. A shielding member is provided on a lower surface of the substrate. The terminals are correspondingly accommodated in the accommodating holes respectively. The terminals include multiple signal terminals and at least one ground terminal. An interval exists between the ground terminal and the shielding member. The ground terminal has a conducting portion extending downward out of a corresponding accommodating hole. The conducting portion is soldered to a main circuit board through a solder, and the solder is in contact with the conducting portion and the shielding member. According to the present invention, the conducting portion of the ground terminal is connected with the shielding member through the solder, thereby reducing a spurious charge, reducing the capacitance, and improving a high frequency.
