To provide a transmission device and a wireless power transmission system, in which an electric field intensity of the circumference of a feeding line is reduced.SOLUTION: A power transmission device comprises: a power transmission electrode unit including a first power transmission electrode and a second power transmission electrode; a power transmission circuit part that supplies an electric power to the power transmission electrode unit; and a feeding line part having a first feeding line connecting the first power transmission electrode with the power transmission circuit part, and a second feeding line connecting the second power transmission electrode and the power transmission circuit part. The power transmission circuit part comprises a matching circuit that increases a voltage amplitude of an AC power. A voltage output from the matching circuit is applied to the power transmission electrode unit through the feeding line part, the first and second feeding lines are adjacently arranged. A voltage component of an inverse phase is applied to each of the first and second feeding lines. A distance between the first feeding line and the second feeding line is shorter than the maximum distance between the adjacent first power transmission electrode and the second power transmission electrode.SELECTED DRAWING: Figure 2
