THIN FILM COIL, CASE ASSEMBLY, NON-CONTACT POWER RECEIVING DEVICE, AND ELECTRONIC DEVICE HAVING THE SAME

摘要

The present invention relates to a thin film coil, a case assembly, a non-contact power receiving device and an electronic device including the same. The thin film coil according to an embodiment of the present invention is a thin film coil disposed at a non-contact power transmitting device for transmitting power wirelessly or a non-contact power receiving device for receiving the power transmitted from the non-contact power transmitting device. The thin film coil comprises: a flexible substrate; a first coil strip formed on one surface of the flexible substrate and including a spiral pattern and a withdrawal pattern withdrawing from one end, which has been arranged in the spiral pattern, to the outside of the spiral pattern; a second coil strip formed on the other surface of the flexible substrate; and a plurality of vias for detour penetrating the flexible substrate at a position adjacent to the withdrawal pattern and connecting the first coil strip and the second coil strip.
