An electrical connector includes an insulating body, a plurality of terminals and a plurality of solder balls. Each terminal has a flat plate portion and two first soldering portions. A receiving slot is formed between the two first soldering portions. Two second soldering portions extend toward each other from lower ends of the two first soldering portions. Each of end portions of the two second soldering portion facing each other respectively bends toward a direction away from a corresponding solder ball to form a bending section. A plate surface of the bending section facing the corresponding solder ball is defined as a matching surface. Along a direction away from the corresponding solder ball, a gap between the two matching surfaces of each terminal becomes smaller. The corresponding solder ball is partially accommodated between the receiving slot and the two matching surfaces. The matching surface abuts against the corresponding solder ball.
