An electrical connector for electrically connecting a chip module to a circuit board includes: an insulating body, provided with a plurality of receiving holes; at least one raised portion, raised on an upper surface of the insulating body, for supporting the chip module at positions without contact pads in the chip module; a metal layer, plated on inner walls of the receiving holes and the upper surface of the insulating body; an insulating layer, disposed to cover the metal layer; and a plurality of terminals, respectively correspondingly received in the receiving holes, each terminal having a contact portion exposed above the receiving hole for conducting to the chip module. When the chip module presses the contact portions downwards, the raised portion urges against the chip module, so as to prevent the chip module from damaging the insulating layer and conducting to the metal layer to cause short circuit.
