A connector has a fitting portion and a cable holding portion. The connector is provided with a signal terminal, a holding member, a cable fixing member and a lower shell. The holding member holds the signal terminal, and the lower shell is attached to the holding member. A cable receiving portion of the lower shell forms the cable holding portion at least in part, and a grounding connection portion forms the fitting portion at least in part. The cable fixing member is fixed to the cable receiving portion, and a cable extends in an intersecting direction from the cable receiving portion. In the intersecting direction, a clamp portion overlaps with the fitting portion.
