  In the case of the conventional coaxial cable contact connection method, the ferrule is mounted on the inner side of the braided wire, and the folded braided wire is placed on the ferrule. The workability when connecting to is not good. In addition, since the braided wire is peeled off and folded, the ferrule is attached, and the braided wire is returned to its original shape, the shape of the braided wire may collapse from its original shape and transmission characteristics may deteriorate. Such a shielded cable harness is required to sufficiently secure the mechanical connection strength between the shielded cable and the electrical connector.

The invention described in this specification has been made by paying attention to such points, and the object of the invention is to caulk a cylindrical body on the outer side of an outer conductor made of a braided wire, and on the outer side of the cylindrical body.
