To provide a wireless charging device with improved charging efficiency and heat dissipation characteristics by applying a three-dimensional magnetic portion, and means of transportation including the same.SOLUTION: A wireless charging device 10 includes a coil portion 200 including a conductive wire, a shield portion 400 disposed on the coil portion 200, and a first magnetic portion 300 disposed between the coil portion 200 and the shield portion 400. The first magnetic portion 300 includes an outer shell portion 310 corresponding to a portion where the coil portion 200 is arranged, and a central portion 320 surrounded by the outer shell portion 310, and the thickness of the outer shell portion 310 may be greater than the thickness of the central portion 320. The heat generated in the magnetic portion can be reduced while increasing wireless charging efficiency by increasing the thickness of the magnetic portion near the coil portion where electromagnetic energy is concentrated during wireless charging, and reducing the thickness of the central magnetic portion where electromagnetic energy density is relatively low.SELECTED DRAWING: Figure 1

    【課題】立体構造の磁性部を適用することにより、充電効率および放熱特性が改善した無線充電装置、およびそれを含む移動手段を提供する。【解決手段】無線充電装置10は、導電性ワイヤを含むコイル部200と、コイル部200上に配置されるシールド部400と、コイル部200とシールド部400との間に配置される第1磁性部300とを含む。第1磁性部300は、コイル部200が配置される部分に対応する外郭部310と、外郭部310によって囲まれる中心部320とを含み、外郭部310の厚さが中心部320の厚さよりも大きくて良い。無線充電中に電磁エネルギーが集中するコイル部近傍の磁性部の厚さを厚くし、相対的に電磁エネルギー密度の低い中心の磁性部の厚さを減らすことにより、無線充電効率を高めながら磁性部で発生する熱を下げることができる。【選択図】図1
