On the other hand, the first braided shield 5a to be provided in the inner side of the metal shield layer 5 is mainly for suppressing internal signal radiation to the external side. Since the high frequency signal transmission cable 1 carries out a high frequency signal transmission of e.g. 10 MHz to 6 GHz, if the mesh size of the braided shield (the space between the wires) is large, the signal radiation to the external side tends to occur. Further, if the outer diameters of the metal wires to be used in the first braided shield 5a are larger than the metal wires to be used in the second braided shield 5b, the high frequency signal transmission cable 1 may be difficult to bend. For that reason, in the first braided shield 5a, it is desirable to use its constituent metal wires 11 with a small outer diameter, and make its mesh size small. In other words, the outer diameters of the metal wires 12 to be used in the second braided shield 5b may be larger than the outer diameters of the metal wires 11 to be used in the first braided shield 5a.
