description Provided is a spiral coil and wireless power transmission and reception circuit including the spiral coil. The spiral coil includes a conducting wire forming one or more coil turns, and a height of one side of the conducting wire in a direction of a central portion of the spiral coil and a height of another side of the conducting wire in an opposite direction to the central portion of the spiral coil in each of the coil turns are different from each other and the conducting wire includes at least one slot formed by an empty space between the one side and the other side, and an upper surface positioned above the one side and the other side and connecting the one side and the other side.
