A power transmission device having a surface a part of which defines a power transmission plane. The device includes: a power transmission coil structure including 2N planar coils laminated in a perpendicular direction to the power transmission plane and wirelessly transmitting AC power to a power receiving device via the power transmission plane and being disposed on a side toward the power transmission plane; and a magnetic substance disposed on a side of the power transmission coil opposite from the power transmission plane, wherein the 2N planer coils constitute coil groups including a coil group in which an i'th closest planar coil to the power transmission plane out of the 2N planar coils and the i'th-closest planar coil to the magnetic substance out of the 2N planar coils are connected in series, and the coil groups are connected in parallel to each other.
