A wireless charging receiver having a wireless charging coil capable of receiving a wireless charging energy using non-contact type magnetic induction and a part for generating a predetermined output power from the wireless charging energy received by the wireless charging coil, the wireless charging receiver comprising:
- a magnetic field insulating sheet;
- a NFC coil coupled with the magnetic field insulating sheet;
- an another coil being provided in an inside space surrounded by the NFC coil and spaced apart from the NFC coil in a mutually insulated state;
- and
- the wireless charging coil being provided in an inside space surrounded by the another coil and spaced apart from the another coil in a mutually insulated state;
- wherein a first circuit path for receiving a data through the NFC coil and a second circuit path for receiving the wireless charging energy through the wireless charging coil are mutually insulated,
- wherein the magnetic field insulating sheet, the NFC coil, the another coil and the wireless charging coil are combined into a set and the set is provided in a portable device, and
- wherein the NFC coil is inactive while the wireless charging coil is active.
