An electrical connector includes an insulating body and multiple conductive terminals. Each conductive terminal has: a main body portion; an elastic arm bending and extending upward from the main body portion; a through slot running through the elastic arm, forming a first elastic arm and a second elastic arm at two opposite sides thereof; and a contact portion bending and extending upward from the elastic arm. A width of the first elastic arm is greater than a width of the second elastic arm. The contact portion defines a virtual center line along an extending direction thereof. A gap between an inner side wall of the first elastic arm on a side thereof adjacent to the through slot and the center line is smaller than a gap between an inner side wall of the second elastic arm on a side thereof adjacent to the through slot and the center line.
