The objective of the present invention is to provide a coil or the like capable of improving efficiency in the form of wireless power transmission even when a high frequency current is used.A power transmission coil TC1 for non-contact power transmission comprises: a power transmission loop coil TL11 wound from an outer circumferential side to an inner circumferential side of the power transmission coil TC1; and a power transmission loop coil TL12 wound from the inner circumferential side to the outer circumference side, wherein the entire shape of the power transmission loop coil TL11 and the power transmission loop coil TL12 in a plan view is the same quadrangle, and in a plan view, the positions of a copper thin film wire TL111 and a copper thin film wire TL112 constituting the power transmission loop coil TL11 when viewed from the center coincides with the positions of a copper thin film wire TL121 and a copper thin film wire TL122 constituting the power transmission loop coil TL12 when viewed from the center.
