A composite functional transmission line is used as a medium for transmitting data between a plurality of electronic devices, and the composite functional transmission line is capable of performing bi-directional data transmissions with the electronic devices directly, and the composite functional transmission line includes a substrate, a plurality of transmission units and an extension unit. Each of the transmission units has two electrical connection terminals, and one of the two electrical connection terminals is provided for connecting the electronic devices, and the other one of the two electrical connection terminals is connected to the substrate, and the extension unit is installed onto the substrate and coupled to the transmission units through the substrate, so that bi-directional data transmissions can be performed between the extension unit and the transmission units.
