    Abstract: A wireless power transmitter according to an embodiment includes a coil and a capacitor which resonate with a wireless power receiver. The coil includes a plurality of cell groups and a core which connects the cell groups with each other. Each of the cell groups includes a plurality of cells. Each of the cells is configured such that magnetic field generated by currents flowing through the cells are formed in a same direction. Each of the cell groups is adjacent to at least one cell group. Each of the cell groups and the core are configured as one conductive wire.

    Abstract: Disclosed is a wireless power transmitter. The wireless power transmitter for transmitting power to a wireless power receiver in a wireless scheme, includes a transmission circuit unit converting power supplied from a power supply unit into power having a frequency for resonance; a transmission induction coil coupling the converted power; and a transmission resonance coil disposed adjacent to the transmission induction coil to transfer the coupled power from the transmission induction coil to the wireless power receiver using the resonance, wherein the transmission circuit unit is vertically spaced apart from the transmission resonance coil.
