PROBLEM TO BE SOLVED: To provide an on-vehicle non-contact charger suppressing an influence upon transponder communication.SOLUTION: When an IG (ignition) of a vehicle 20 is switched from an off state to an on state, transponder communication between a transponder 15 and an immobilizer device 21 may be executed. WHen determining that the IG is switched from the off state to the on state through an IG switch 29a, a charge control circuit 41 suspends power supply to a primary coil L1 over a constant time period in which the transponder communication is executed, to thereby suppress an influence upon the transponder communication due to a radio wave from a non-contact charger 40 caused by charging operation. |
