PROBLEM TO BE SOLVED: To provide a vehicle electric power charge and supply system capable stably transmitting electric power to a vehicle irrespective of misalignment of the vehicle in right/left direction.SOLUTION: A power transmission antenna 105 which is disposed on a road face and a power reception antenna 107 which is disposed on the bottom face of a vehicle 101 resonate with each other at an identical resonant frequency and establish a magnetic field coupling. When the power reception antenna 107 enters an area where the power transmission antenna 105 is positioned, the electric power is transmitted. Stable transmission characteristics are obtained when the distance H between the power transmission antenna and the power reception antenna facing to each other is within a range of 0.11×W1≤H≤0.26×W1 with respect to a width W1 of the power transmission antenna area.SELECTED DRAWING: Figure 1A

    【課題】車両の左右方向位置ずれに対して、車両用充給電システムの伝送特性が不安定である。【解決手段】路面側に配置された送電アンテナ105と車両101の底面に配置された受電アンテナ107とが該等しい共振周波数で共振し磁界結合する。送電アンテナ105が位置する領域上に受電アンテナ107が侵入した際に送電がなされる。送電アンテナと受電アンテナとの対向距離Hが、送電アンテナエリア幅W1に対して、0.11×W1≦H≦0.26×W1の範囲内に設定されることにより、安定した伝送特性が得られる。【選択図】図1A
