Abstract: Provided is a cable connector, a cable assembly, and a method of manufacturing the cable assembly, in which electric characteristics are stabilized by suppressing elastic deformation of a cable for differential signal transmission, and besides, which is easily connectable by reducing the number of parts. In a ground contact, an outer-conductor adhering portion which is protruded from a side wall portion of a connector main body and which is adhered with an outer conductor by a conductive adhesive is provided. In this manner, elastic deformation of a cable for differential signal transmission is suppressed, so that electric characteristics can be stabilized. Also, connecting work between the outer conductor and the ground contact can be simplified as reducing the number of parts. Further, the cable for differential signal transmission is not exposed to a high temperature of soldering or others, and therefore, thermal deformation thereof does not occur, either.
