Abstract
A power reception device includes: a housing including a first surface facing in a first direction, a second surface facing in a second direction opposite to the first direction, and a side surface surrounding a space between the first surface and the second surface; a coil antenna wound in a circle; a shielding sheet disposed over the coil antenna; and a first magnet and a second magnet adjacent to an outermost coil of the coil antenna and disposed to be spaced apart from the outermost coil. The first magnet is disposed so that a portion of magnetism induced by the first magnet is formed in the first direction. The second magnet is disposed so that a portion of the magnetism induced by the second magnet is formed in a third direction that is an outside direction from a center of the coil antenna.
