[Problem] To provide a power transmission system by which large declines in power transmission efficiency may be avoided, even in instances of deviation between the transmitting antenna and the receiving antenna. [Solution] This power transmission system (100) has a transmitting antenna (105) situated on the ground and including a wound transmitting coil, and a receiving antenna (201) for receiving electrical energy from the transmitting antenna (105) through the agency of an electromagnetic field, arranged facing the transmitting antenna (105) and including a wound receiving coil, and is characterized in that the surface area (S1) of a first projection plane formed in the vertical direction with respect to a horizontal plane by the transmitting coil is greater than the surface area (S2) of a second projection plane formed in the vertical direction with respect to a horizontal plane by the receiving coil. |
