PROBLEM TO BE SOLVED: To provide a wireless power transmission system that drastically suppresses leakage of electromagnetic noise at the time of wireless power transmission.SOLUTION: A wireless power transmission system 10 includes: a wireless power supply device 100 including an electromagnetic shield dome 140 disposed so as to cover a power supply coil unit 130's surroundings; and a wireless power reception device 200 including a lifting/lowering operation unit 230 for vertically movably holding a power reception coil unit 210. The electromagnetic shield dome 140 includes: an installation part 141 on which the power supply coil unit 130 is installed; a side wall part 142 erected along the outer edge of the installation part 141; and an aperture through which the power reception coil unit 210 can pass. The lifting/lowering operation unit 230, in performing power transmission, moves the power reception coil unit 210 to store the power reception coil unit 210 inside the electromagnetic shield dome 140.SELECTED DRAWING: Figure 6 |
