The invention relates to a vertical super-flat wire coil. The critical point of the formation method of the vertical super-flat wire coil lies in that metallic conductors are firstly used to make coils and then insulating layers are processed on the surfaces of the coil conductors according to the demand of the optimized coil performance, which overthrows the traditional coil fabrication process of adopting insulated wires to make coils; since the fabrication of coils is out of limitation of insulated varnish and formed wires, the optimized performance of coils is completely achieved: for instance, since the width-to-thickness ratio is not limited, the width-to-thickness ratio can be increased to any degree ( one to several hundred or thousand or even over ten thousand); since the corner radius is not limited, a right angle also can be achieved; since the shapes of the coils are irregular, the coils can be changed into any shape; since the thickness is adjustable, thickness of each layer of wires can be different.
