An electrical connector includes an insulating body and a plurality of first terminals, disposed side by side in the insulating body. The insulating body is formed with at least two bridging-portion removal holes. Bridging portions between the first terminals are capable of being removed through the bridging-portion removal holes. The at least two bridging-portion removal holes are respectively formed through plate surfaces of the insulating body, and the at least two bridging-portion removal holes are arranged in a staggered manner in a front-to-rear direction.
