An electrical connector includes an insulating body and a row of terminals formed by cutting a metal sheet. The insulating body has a base board defining a row of terminal cavities. Each of the terminal cavities includes a fixing cavity. A plurality of exit cavities each is formed between two adjacent fixing cavities. The terminals are insert molded to the base board and have respective plate-shaped fixed portions spaced from each other. Each adjacent two fixed portions have two pairs of inner connecting arms protruded from the fixed portions towards each other and spaced with each other. The fixed portions and the inner connecting arms are embedded in the corresponding fixing cavities. Each adjacent two pairs of the inner connecting arms are formed by cutting out a middle part of an inner connecting portion which connects corresponding portions of each adjacent two fixed portions from the corresponding exit cavity.
