An electrical connector includes a base and terminals. The base is formed with terminal slots in which the terminals are disposed. Each terminal slot has first and second walls, and third and fourth walls. Each terminal includes a fixing portion, an elastic arm and a pin portion. The fixing portion presses against and is positioned by the terminal slot. The fixing portion has first and second plates that are folded. The first plate contacts the first wall of the terminal slot. The elastic arm is connected to a top of the second plate. The elastic arm extends upward in a direction toward the fixing portion. A connection point is formed on the elastic arm close to a free end of the elastic arm. The pin portion, which is formed by prodding and pressing the fixing portion, extends toward a bottom of the base.
