1. A chip-type coiled component comprising:
- an insulating member having an upper face and a lower face;
a magnetic layer provided on at least one of the upper and lower faces of said insulating member; and
a conductive member provided in said insulating member and having a plurality of turns forming a three-dimensional spiral shape extending from one end of said conductive member towards the other end of said conductive member, wherein the turns of said conductive member are gradually different, in diameter, from each other from one end of said conductive member towards the other end of said conductive member such that at least the turns of said conductive member are each disposed in different planes.
