Abstract
Disclosed herein is a reception device for wireless charging. The reception device for wireless charging may include a reception antenna configured to generate an electric current based on a change of magnetism and a charging circuit unit configured to convert the electric current generated by the reception antenna into direct current. The reception antenna and the charging circuit unit may be connected to a flexible board. Accordingly, the reception device can be attached to the casing of a smart terminal while minimizing a change in the thickness of the smart terminal. A task for connecting the antenna and charging circuit unit of the reception device can be eliminated. A wireless charging function can be assigned to a smart terminal by simply replacing the casing of the smart terminal not having the wireless charging function.
