A power transmitting system in an embodiment is usable in a wireless power transmission system based on an electric field coupling method. The power transmitting system includes a first power transmitting device; and a second power transmitting device. The first power transmitting device includes a first power transmitting electrode pair, and a first matching circuit connected with the first power transmitting electrode pair. The second power transmitting device includes a second power transmitting electrode pair, and a second matching circuit connected with the second power transmitting electrode pair. A parasitic capacitance between the electrodes of the first power transmitting electrode pair is smaller than a parasitic capacitance between the electrodes of the second power transmitting electrode pair. The first matching circuit has a parallel capacitance larger than a parallel capacitance of the second matching circuit.
