An electric connector comprises a base connector fitted to a surface of a circuit board and a socket connector connected to ends of wires. The base connector includes a base housing having a mounting surface and two rows of base contacts. The socket connector includes a socket housing to be fitted to the base housing in a predetermined fitting direction perpendicular to the mounting surface, and two rows of socket contacts. Each of the base contacts has a fork-like shape including semi-fixed piece portion and a resilient piece portion. The resilient piece portion of each base contact is restrained from displacing by an intermediate wall of the base housing. The semi-fixed piece portion of each base contact is received by a side wall of the base housing.
