Claim 7:
8. A power transmission device, comprising:
a power transmission coil including a coiled conductive wire and defining an opening; and
the foreign object detection device according to claim 3, wherein
the coils are disposed to cover a coil surface of the power transmission coil,
a distance between the surface of the substrate provided with the first connecting line and the coil surface of the power transmission coil is larger than a distance between the surface of the substrate provided with the second connecting line and the coil surface of the power transmission coil, and
the first connecting line and the second connecting line are arranged such that the first connecting line is located at a position closer a center of the coil surface of the power transmission coil than the second connecting line, in a region facing an outer peripheral region of the power transmission coil as viewed from a direction orthogonal to the coil surface of the power transmission coil.
