PROBLEM TO BE SOLVED: To provide a non-contact power transmission device capable of magnetically coupling a power transmitting coil and a power receiving coil and stably charging a movable traveling body even without providing the power transmitting coil on a road surface while overlapping the road surface and even in a state where the power receiving coil is spread over the adjacent power transmitting coils in the movable traveling body.SOLUTION: A non-contact power transmission device is provided in a movable traveling body in which multiple power transmitting coils are provided while being spaced apart from each other in a length direction and a power receiving coil is moved in the length direction of the power transmitting coils. The power receiving coil is formed longer than the power transmitting coils in the length direction. In a state where the power receiving coil is spread over two power transmitting coils, magnetic field coupling can be performed between the power transmitting coils and the power receiving coil.SELECTED DRAWING: Figure 1 【課題】路面に送電用コイルを重畳して設けなくても、移動走行体が受電用コイルが隣接する送電用コイルの間に跨った状態でも、送電用コイルと受電用コイルの間の磁気結合が可能であり、安定して移動走行体を充電可能する非接触電力伝送装置を提供する。【解決手段】非接触電力伝送装置は、送電用コイルが長尺方向に沿って互いに間隔を設けて複数設けられ、受電用コイルが送電用コイルの長尺方向に沿って移動する移動走行体に設けられ、受電用コイルが送電用コイルより長尺方向において長くなるように形成され、受電用コイルが２つの送電用コイルに跨った状態において、送電用コイルと受電用コイルの間で磁界結合できるように構成されている。【選択図】図１
