Abstract
A power transmission device has a short height and a small size and is capable of transmitting high power with high efficiency. The power transmission device includes first resonators, second resonators coupled to the first resonators via electromagnetic waves, a primary circuit connected to an input end of the first resonator, and a secondary circuit connected to an output end of the second resonator. The first resonator is insulated from the second resonator. Output impedance of the primary circuit is different from input impedance of the secondary circuit. Impedance matching is performed between the output impedance of the primary circuit and impedance in the case of viewing the first resonator side from the input end of the first resonator, and impedance matching is performed between the input impedance of the secondary circuit and impedance in the case of viewing the second resonator side from the output end of the second resonator.
