A surface communication device includes: a sheet-shaped electromagnetic wave propagation unit that propagates electromagnetic waves; and a power supplying device unit or a power receiving device unit that is disposed above the electromagnetic wave propagation unit in a non-conductive state with the electromagnetic wave propagation unit, and includes an electromagnetic wave coupling unit that transmits electromagnetic waves to the electromagnetic wave propagation unit or receives electromagnetic waves from the electromagnetic wave propagation unit. The electromagnetic wave coupling unit includes a dielectric resonator that strengthens an electromagnetic coupling between the electromagnetic wave coupling unit and the electromagnetic wave propagation unit.
