[Problem] To provide a power transmission system capable of efficiently transmitting power in the cases of charging a battery (204) using a power receiving-side system. [Solution] A power transmission system (100) of the present invention is configured at least from: a power transmitting antenna (105), which constitutes a series resonator having an inductance component (L1) and a capacitance component (C1), and which has alternating current power inputted thereto; a power receiving antenna (201), which constitutes a series resonator having an inductance component (L2) and a capacitance component (C2), and which receives electromagnetic energy from the power transmitting antenna (105) via an electromagnetic field; a rectifying section, which rectifies output from the power receiving antenna (201) to direct current power, and which outputs the direct current power; and a load for inputting the output from the rectifying section. The power transmission system is characterized in that, when the power transmission system is used within a range wherein a load resistance value (R) satisfies formula Rmin<=R<=max in the cases including a case where a coupling coefficient between the power transmitting antenna (105) and the power receiving antenna (201) is k, there are predetermined relationships among respective components and the coefficient.
