Disclosed is an electric connector for electrically connecting a chip module to a circuit board. The electric connector comprises an insulation body and at least one terminal, wherein at least one accommodating hole which runs through up and down is formed in the insulation body; each accommodating hole correspondingly accommodates one terminal; each terminal has a contact part at the upper end and a welding part at the lower end; the welding part extends downwardly out of the corresponding accommodating hole; the welding part has a welding surface and a solder resist layer for surrounding thewelding surface; the welding surface is used for combining a soldering flux; and the solder resist layer is used for blocking diffusion of the soldering flux on the solder resist layer.
