ABSTRACT:
To provide a planar inductor that can be easily designed in any size without restricting coil characteristics, that supplies the necessary power corresponding to the area when a pair of inductors are placed facing each other to carry out non-contact power transmission, and that has greater design flexibility that allows for setting separation cut-off lines with relative freedom.A planar inductor comprising a flat coil support layer that supports multiple flat coils arrayed in a plane and a first interconnection layer provided on one side of said flat coil support layer and a second interconnection layer provided on the other side of the flat coil support layer, wherein each flat coils start point is connected through the first interconnection layer and each flat coils end point is connected through the second interconnection layer, and a parallel electrical connection of the multiple flat coils arrayed in a plane is thereby achieved between the first interconnection layer and the second interconnection layer.
