Abstract
A coil element according to the present invention includes a plurality of first conductive materials formed on a base material at a predetermined pitch, an insulation material superposed on the first conductive materials, and a plurality of second conductive materials formed on the insulation material at a predetermined pitch, wherein the first conductive materials and the second conductive materials are alternately connected to each other while interposing the insulation material between the both to form a three-dimensional coil. By properly selecting a pitch, a width, or a length of the coil, it is possible to easily realize a desired high inductance vale even though a pattern area is small.
