To provide a coil and the like that can reduce the weight while reducing various costs as a coil for wireless power transmission, and can improve the transmission efficiency as a coil and prevent the operating temperature from rising.SOLUTION: In a power receiving loop coil RL1 used for non-contact type power transmission and composed of winding of a copper thin film wire RL11 and a copper thin film wire RL12, the thickness of a portion of a copper thin film wire RL11 and the copper thin film wire RL12 having relatively high density of a current flowing during power transmission is configured to be thicker than the thickness of a portion of the copper thin film wire RL11 and the copper thin film wire RL12 having relatively low density of the current.SELECTED DRAWING: Figure 2

    【課題】ワイヤレス電力伝送用のコイルとしての諸コストを低減しつつ軽量化することができると共に、コイルとしての伝送効率の向上と動作温度の上昇の防止が可能なコイル等を提供する。【解決手段】非接触型の電力伝送に用いられ且つ銅薄膜線RL11及び銅薄膜線RL12の巻回により構成される受電ループコイルRL1において、電力伝送の際に流れる電流の密度が相対的に高い銅薄膜線RL11及び銅薄膜線RL12の部分の厚さが、当該密度が相対的に低い銅薄膜線RL11及び銅薄膜線RL12の部分の厚さよりも厚いように構成される。【選択図】図2
