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.
【課題】電力伝送効率の低下を抑制し、車両本体に対して漏洩する電磁波を抑制する。【解決手段】車両9の底部に設けられた受電回路に対してワイヤレスで給電される電力を受け取る受電システムは、基準軸X3の周りに導体線を周回させて形成され、磁界を介して伝送される電力を受け取る受電側アンテナコイル34と、基準軸X3に沿った非伝送方向D2の側において、受電側アンテナコイル34の径方向に沿って配置された磁性材製の第1シールド板81と、を備えた受電側アンテナコイルユニット30と、車両9の車体底面9bの凹部9cを含む対象領域の凹凸形状に沿った形状を有し、この対象領域に配置された導電材製の第2シールド板82と、を備え、受電側アンテナコイルユニット30が、基準軸X3に沿った方向に見て、凹部9cと重複する位置に配置されている。【選択図】図5
