The present invention provides a mobile terminal which, when wireless (contactless) charging of a battery is performed by approximating a transmission coil of a charging unit (charging pad) and a reception coil provided in a wireless charging module of a mobile terminal, can adjust the saturation magnetic flux density and eddy currents of a shield sheet to which the reception coil is attached, the shield sheet being provided in the wireless charging module. When the reception coil is placed on the shield sheet to perform wireless charging, the saturation magnetic flux density and eddy current generation in the shield sheet are adjusted for wireless charging purpose because a part of the region in which the magnetic flux density is most quickly saturated was clipped off from the shield sheet. Thus, charging efficiency can be increased, and the problem of heat generation of the shield sheet can be effectively.
