A coil capable of improving efficiency in the form of wireless power transmission even when a high frequency current is used. A power transmission coil for non-contact power transmission includes: a power transmission loop coil wound from an outer circumferential side to an inner circumferential side of the power transmission coil; and a power transmission loop coil wound from the inner circumferential side to the outer circumference side, wherein the entire shape of the power transmission loop coil and the power transmission loop coil in a plan view is the same quadrangle, and in a plan view, the positions of a copper thin film wire and a copper thin film wire constituting the power transmission loop coil when viewed from the center coincides with the positions of a copper thin film wire and a copper thin film wire constituting the power transmission loop coil when viewed from the center.
