An electric connector includes connector bodies in which connection terminal trains are arranged in a coplanar fashion in male and female connector housings; and a ground connection fitting that is equipped therein so as to extend between the connection terminal trains in a train direction. At least one connector body has a conductive reinforcement fitting that extends along the connector housing. The ground connection fitting has ground connection portions that are exposed to the side of a board facing surface of the corresponding connector housing of the connector body; and reinforcement fitting connection portions that are connected to the reinforcement fitting on both outsides of the connection terminal trains in the train direction.
