Provided is a power transmission system that can prevent a plunge in power transmission efficiency even when there is a positional shift of a power reception antenna with respect to a power transmission antenna. A power transmission system 100 of the present invention is characterized by including: a power transmission antenna 105 that includes a wound power transmission coil that is placed on the ground; and a power reception antenna 201 that is disposed in such a way as to face the power transmission antenna 105 , includes a wound power reception coil, and receives electric energy from the power transmission antenna 105 via an electromagnetic field, wherein an area (S 1 ) of a first projection plane that is formed by the power transmission coil in a vertical direction with respect to a horizontal plane is larger than an area (S 2 ) of a second projection plane that is formed by the power reception coil in the vertical direction with respect to the horizontal plane.
