Abstract
A wireless charging device according to one embodiment comprises two types of magnetic parts having different magnetic properties, wherein the two types of magnetic parts can be appropriately arranged to effectively disperse heat, generated during wireless charging, through the distribution of magnetic flux, and improve durability against external shock or distortion. Accordingly, the wireless charging device may be usefully used in a transportation means, such as an electric vehicle, that requires a large amount of power transmission between a transmitter and a receiver.
