PROBLEM TO BE SOLVED: To provide a wireless power supply device and a wireless power transmission system that drastically suppress leakage of electromagnetic noise at the time of wireless power transmission.SOLUTION: A wireless power supply device 100 comprises: a power supply coil unit 130 including a power supply coil 131 that receives power from a power source 110 to generate an AC magnetic field; and an electromagnetic shield dome 140 disposed so as to cover the power supply coil unit 130's surroundings. The electromagnetic shield dome 140 includes: a bottom part 141 on which the power supply coil unit 130 is disposed; side wall parts 142 (first to fourth side wall parts 143, 144, 145, 146) erected along the outer edge of the bottom part 141; and a lid part 147 opposing the bottom part 141 so as to interpose the power supply coil unit 130 between the lid part and the bottom part. The first side wall unit 143 includes an entry aperture through which a power reception coil unit 210 including a power reception coil 211 for receiving power from the power supply coil 131 through the AC magnet field can enter.SELECTED DRAWING: Figure 6
