Abstract: A mobile terminal is provided, which includes a wireless charging module, a battery pack, and a circuit board substrate. The wireless charging module includes a charging coil formed of a wound conducting wire and a communication coil placed adjacent to the charging coil. The wireless charging module has a substantially planar shape. The battery pack has a substantially planar shape and is configured to store power from the wireless charging module. The circuit board substrate is configured to control operation of the mobile terminal. The wireless charging module overlaps with each of the circuit board substrate and the battery pack.

Abstract: A contactless connector apparatus is provided with a first coil closely opposed to a second coil so as to be electromagnetically coupled thereto. The first coil includes: an inner transmitter coil wound around an axis passing through its center; and an outer transmitter coil wound around the axis and outside the inner coil. One end of the outer transmitter coil is connected to one end of the inner transmitter coil such that, when a current flows through the transmitter coils, a direction of a loop current generated around the axis by a current flowing through the inner transmitter coil is opposite to that of a loop current generated around the axis by a current flowing through the outer transmitter coil. A self-inductance of the outer transmitter coil is larger than that of the inner transmitter coil.
