The purpose of the invention is to facilitate mounting of a power receiving coil on a vehicle and also extend the allowable range of the positional shift of the power receiving coil with respect to a power supplying coil to prevent a power supply efficiency from lowering. A power supplying device (100) uses electromagnetic force to supply power to a vehicle (130) having a power receiving coil (153a) and has a power supplying coil (103a) facing the power receiving coil (153a) and supplying power thereto. The power supplying coil (103a) has substantially the same shape as the power receiving coil (153a) and has a first length longer than a second length, said first length being the length in the right and left direction of the vehicle (130), said second length being the length in the front and rear direction of the vehicle (130).
