PROBLEM TO BE SOLVED: To suppress reduction in power transmission efficiency and suppress an electromagnetic wave leaking in a vehicle main body.SOLUTION: A power reception system for receiving power wirelessly supplied to a power reception circuit installed on the bottom of a vehicle 9 comprises: a power reception side antenna coil unit 30 comprising a power reception side antenna coil 34 formed so as to wind a conductor wire around a reference axis X3 to receive power transmitted through a magnetic field and a first shield plate 81 that is made from magnetic material and is arranged along the radial direction of the power reception side antenna coil 34 on the non-transmission direction D2 side along the reference axis X3; and a second shield plate 82 that is made from conductive material, has a shape along a convexo-concave shape of a target area including a concave part 9c of a vehicle body bottom surface 9b of the vehicle 9, and is arranged in the target area. The power reception side antenna coil unit 30 is arranged at a position overlapping with the concave part 9c when being viewed in the direction along the reference axis X3. |
