Zusammenfassung:	The present embodiment relates to a coil device and a wireless charging device including the same. The coil device according to the present embodiment includes: a coil wound to form a hollow portion; and a shielding housing including a flat part on which the coil is disposed, an inner wall corresponding to a shape of the hollow portion, and an outer wall corresponding to an outer circumferential shape of the coil. The inner wall protruding from the flat part on which the coil is disposed may have a height of 0 to 1.5 times a height of the coil. An inductance of the coil may have a range of 9.2 μH to 12.26 μH.
