1. A common mode filter, comprising:
- a primary coil that includes a primary coil body forming a plane in a vortex structure; and
a secondary coil that includes a secondary coil body forming a co-plane in the same vortex structure as the primary coil body and forms a 180°
rotational symmetry with the primary coil body, having the same length, width, and turn number as the primary coil body; and
wherein when an interval between the primary and secondary coil bodies is S and the width of the primary and secondary coil bodies is W, the primary and secondary coil patterns are formed so as to meet 0.25≦
S/(W+S)≦
0.75.

Abstract
Disclosed herein are a common mode filter and a method of manufacturing the same. The common mode filter includes: a primary coil that includes a primary coil body forming a plane in a vortex structure; and a secondary coil that includes a secondary coil body forming a co-plane in the same vortex structure as the primary coil body and forms a 180° rotational symmetry with the primary coil body, having the same length, width, and turn number as the primary coil body. Further, the method of manufacturing a common mode filter is proposed.
