An electrical connector that can provide stable contact between a signal transmission terminal and a short-circuit terminal even if the connector is downsized. The connector includes a main body having a plurality of terminal receiving cavities provided with lances by which signal transmission terminals are secured and a plurality of short-circuit terminal receiving cavities adjacent to the terminal receiving cavities for receiving short-circuit terminals. Each short-circuit terminal includes a bent part at a forward position and a contact at a rearward position. The main body further includes a window that is formed at a position to the rear of the lances corresponding to the contacts of the short-circuit terminals and through which the terminal receiving cavities and the short-circuit terminal receiving cavities communicate with each other. The contacts of the short-circuit terminals are in contact with the female terminals through the window.
