Patent ID: 7453344

Claim:
A multilayer coil component comprising: a first coil unit including a plurality of coil conductors and a plurality of ceramic layers that are laminated and including a first helical coil; a second coil unit including a plurality of coil conductors and a plurality of ceramic layers that are laminated and including a second helical coil; and a laminated body including the first coil unit stacked on the second coil unit in a lamination direction; wherein the first helical coil and the second helical coil are coaxially positioned, are electrically connected to each other in parallel, and have different numbers of turns; the sum of turns of the coil conductors of the first and second helical coils which are opposed to each other at a portion where the first and second coil units are adjacent to each other is larger than the sum of turns of the coil conductors of the first and second helical coils positioned on both outer sides in the coil axis direction; and an input leading electrode of either one of the first and second helical coils and an output leading electrode of the other of the first and second helical coils are adjacent to each other in the lamination direction.
