Abstract
A coil component includes a primary winding generating a magnetic field by current input from outside, and a secondary winding an induced current generated by the magnetic field passes. The primary winding includes ring-shaped primary first/second turns as viewed in first direction. The secondary winding includes ring-shaped secondary first/second turns as viewed in first direction. The primary and secondary first turns are alternately arranged in first direction to form a first tubular portion. The primary and secondary second turns are alternately arranged in first direction to form a second tubular portion. The second tubular portion is located inside the first tubular portion as viewed in first direction. The input current in each primary first turn and the input current in each primary second turn flow in the same direction.
