PROBLEM TO BE SOLVED: To establish circuit connection with a simple configuration and to eliminate the contortion of a charging cable regarding to an external charging cable.SOLUTION: A charging cable 25 contains therein, a plurality of first conductive wires 1 connected to an external power supply side and a plurality of second conductive wires 2 connected to a vehicle side at the time of external charging for charging a vehicle from an external power supply. One group of conductive wires among the first conductive wires 1 and the second conductive wires 2 is connected with a stationary part 4, and the other group of conductive wires is connected with a rotation part 5. The stationary part 4 and the rotation part 5 form a rotary contact 3. The rotary contact 3 rotatably connects a first conductive wire 1 and a second conductive wire 2. In addition, a rotational position sensor 8 detects the rotational position of the rotation part 5 to the stationary part 4 at the rotary contact 3. Furthermore, a switch circuit 13 is placed on each of one group of conductive wires, any conductive wire from the one group of conductive wires is selected on the basis of the rotational position detected by the rotational position sensor 8 and an electric conduction state is switched.
