Abstract
Disclosed herein are a multi wireless charging apparatus and a method for manufacturing the same. The multi wireless charging apparatus includes: a control unit wholly controlling a multi wireless charging process; and a plurality of wireless charging units electrically connected with the control and deformed into a roll form by being bonded so as to a plurality of interlayer voids at the time of laminating a plurality of flexible substrates. By this configuration, the multi wireless charging apparatus can be rolled up in a roll form while having a slim thickness and therefore, can be conveniently carried.
