A mobile terminal is provided with a housing, a circuit board included in the housing and having a thickness direction normal to a plane of the circuit board, a battery pack included in the housing, and a non-contact charging module included in the housing. The non-contact charging module includes a charging coil formed of a wound conducting wire; a communication coil arranged adjacent to the charging coil; and a magnetic sheet on which the charging coil and the communication coil are arranged. The magnetic sheet has four edges that collectively define a rectangular profile of the magnetic sheet, and at most three pairs of adjacent edges respectively meet to form at most three corners. At least a portion of the non-contact charging module overlaps with the circuit board as viewed in the thickness direction of the circuit board.

A coil module is disposed inside an electronic apparatus and receives prescribed power. The coil module includes a loop coil, a plate-like magnetic body that is disposed on the loop coil, and a conductive member that has prescribed conductivity and is disposed parallel with the plate-like magnetic body and on a surface, opposite to a surface on which the loop coil is disposed, of the magnetic body. The conductive member projects outward relative to at least a portion of a circumferential surface of the magnetic body.

Cell phone having wireless charging function

A mobile terminal is provided with a housing having a rectangular shape in a plan view of the housing defined by two short sides along a lateral direction and two long sides along a longitudinal direction. A camera, a battery, and a circuit board are included in the housing. A wireless charging coil is arranged in the housing and includes a winding portion and two leg portions. A sheet is arranged in the housing. The sheet has a rectangular shape including four edges and four corner portions, wherein each pair of adjacent edges forms a virtual corner, each corner portion is receded inwardly from its corresponding virtual corner by a receding distance, and one of four receding distances is greater than other three of the four receding distances.

A first connection circuit () is adjusted to cancel out mutual coupling impedance occurring between a first antenna element () in a first frequency band and a second antenna element () in a second frequency band, and reduces a degradation occurring due to the coupling between the antenna elements. A second frequency band cutoff circuit () for the second frequency band is provided between the first antenna element () and the first feeding portion ().
