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.
