An electric power transmission system can include: a power transmission antenna that constitutes a series resonator with an inductance component of L1 and a capacitance component of C1, and to which AC power is input; a power receiving antenna that constitutes a series resonator with an inductance component of L2 and a capacitance component of C2, and which receives electromagnetic energy from the power transmission antenna via electromagnetic fields; a rectifying unit that rectifies an output of the power receiving antenna to output DC power; and a load to which an output of the rectifying unit is input, wherein, at times including when a coupling coefficient between the power transmission antenna and the power receiving antenna is k, if a load resistance value is R, the following relationships are established: L 1  C 1 = L 2  C 2 ; L 1 C 1 > L 2 C 2 ; and   k  L 2 C 2 ≥ R .
