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.
Claims6
A method for manufacturing a coil element comprising the steps of:
- printing a plurality of first conductors on a base material;
- printing an insulation material on said base material to cover said first conductors except for opposite ends of said first conductors;
- and
- printing a plurality of second conductors on said insulation material at a predetermined pitch to be alternately conductive to the opposite ends of said first conductors;
- wherein said first conductors and said second conductors are alternately connected to each other while interposing said insulation material between the both, to form a three-dimensional coil.
