MULTILAYER COIL COMPONENT

摘要

A multilayer coil component is constructed such that inductance can be finely adjusted and the coupling between two helical coils can be strengthened without increasing the types of patterns of coil conductors. Coil conductors (13a to 13e) of a first coil unit (21) are connected to each other in series via via-hole conductors (15) so as to form a first helical coil (L1). Coil conductors (13f, 13d, and 13e) of a second coil unit (22) are connected to each other in series via via-hole conductors (15) so as to form a second helical coil (L2). The first and second helical coils (L1 and L2) are coaxially positioned, have different numbers of turns, and are electrically connected to each other in parallel. The sum of turns of the coil conductors (13e and 13f)facing each other at a portion where the first coil unit (21) and the second coil unit (22) are adjacent to each other is larger than the sum of turns of the coil conductors (13a and 13e) positioned on both outer sides in the coil axis direction of the first and second helical coils (L1 and L2).
