Abstract: The present disclosure relates to a wireless power reception device and method, and provides a wireless power reception device comprising: a secondary coil which is magnetically coupled to a primary coil disposed in a wireless power transmission device so as to receive wireless power from the wireless power transmission device; a shielding member for supporting the secondary coil; a power pickup unit including a rectifier circuit for rectifying an alternating current signal according to the wireless power received by the secondary coil into a direct current signal; and a communication/control unit for controlling transmission of the wireless power and communicating with the wireless power transmission device. On the basis of a secondary coil and a shielding member according to the present embodiment, slimming of an applied product can be achieved and, simultaneously, the same target performance index (which is required for the standard medium power level (for example, 60 W)) can be implemented.
