PROBLEM TO BE SOLVED: To provide a wireless power charging system which performs non-contact power transmission and protects a charging device and a battery pack from a magnetic field by the shielding members of a primary side core and a secondary side core and an overcurrent reducing member. SOLUTION: The wireless power charging system includes: a wireless power transmitter 10 in which a power signal is wirelessly transmitted from a primary side core 14 via a resonant converter 13 by control of a transmission control part 12; and a wireless power receiver 20 for receiving the wireless power signal transmitted from the primary side core 14 of the wireless power transmitter 10 via a secondary side core 24 to charge the power in a battery cell 21 by control of a reception control part 22. The wireless power receiver 20 includes a receiving shielding panel 25 and an overcurrent reducing member 26 on the secondary side core 24 to shield a magnetic field generated from the secondary side core 24.
