PROBLEM TO BE SOLVED: To provide a power transmission system capable of avoiding heating of a vehicle bottom section and improving power transmission efficiency of a system.SOLUTION: A power transmission system 100 includes: a wound transmission antenna including a wound transmission coil mounted on the ground; a wound power-receiving coil disposed to oppose the transmission antenna; and a power-receiving antenna receiving electric energy from the transmission antenna through an electromagnetic field. The transmission coil includes: a first base material 710 with a first thickness (d1); a second base material 720 with a second thickness (d2) different from the first thickness; a plurality of high-magnetic permeability members 730 arranged between the first base material 710 and the second base material 720; and a conductor wire wound around the first base material 710 and the second base material 720. |
