A leakage magnetic field shielding device comprises: a leakage magnetic field determining unit for determining phase and magnitude of a leakage magnetic field based on information obtained from a power supply device and a current collector device; a shielding current controller for determining a shielding current based on the phase and magnitude of the leakage magnetic field and supplying the determined shielding current to the leakage magnetic field shielding device; and a shielding unit for shielding the leakage magnetic field by generating a shielding magnetic field in accordance with the supply of the shielding current. The shielding unit has a multiple resonance characteristic depending on an arrangement of capacitors and coils and is disposed to surround the power supply device or the current collector device. The shielding magnetic field has resonance frequencies canceling magnetic fields corresponding to fundamental frequency and multiple frequency of the leakage magnetic field.
