To suppress impact on a vehicle periphery and a vehicle component due to a magnetic field at non-contact charging in an electric vehicle and a drive unit that can be charged in a non-contact manner.SOLUTION: A motorcycle 1 includes: a rear wheel 4; a swing arm 21 for supporting the rear wheel 4; a motor 30 for driving the rear wheel 4; and a PCU 45 for controlling the motor 30, where the motor 30 and the PCU 45 are mounted to the swing arm 21. The motorcycle includes: a battery 40 serving as a drive power source for the motor 30; and a secondary coil unit 56 for charging the battery 40 in a non-contact manner. The secondary coil unit 56 includes an opposed surface 56a to be subjected to induction field by being opposed to a primary coil unit on an outside of the vehicle in an outside part of the swing arm 21 which faces the outside in a horizontal direction. The PCU 45 and the secondary coil unit 56 are mutually disposed on horizontally reverse sides while interposing a vehicle body horizontal center CL therebetween.SELECTED DRAWING: Figure 2 【課題】非接触充電が可能な電動車両及び駆動ユニットにおいて、非接触充電時の磁場による車両周辺および車両部品への影響を抑える。【解決手段】後輪４と、後輪４を支持するスイングアーム２１と、後輪４を駆動するモータ３０と、モータ３０を制御するＰＣＵ４５と、を備え、モータ３０およびＰＣＵ４５がスイングアーム２１に搭載される自動二輪車１であって、モータ３０の駆動電源であるバッテリ４０と、バッテリ４０の非接触充電用の二次コイルユニット５６と、を備え、二次コイルユニット５６は、スイングアーム２１における左右方向外側に臨む外側部に、車両外部の一次コイルユニットと対向して誘導磁場を受ける対向面５６ａを有し、ＰＣＵ４５および二次コイルユニット５６は、車体左右中心ＣＬを挟んで互いに左右逆側に配置されている。【選択図】図２
