Summary:To provide a laminate coil component which can improve a high frequency characteristic and reduce the DC resistance of a coil while maintaining large inductance.SOLUTION: A laminate coil component 1 includes: an element assembly; a first coil C1 and a second coil C2 respectively arranged in the element assembly and having a coil axis along a second direction D2; and a pair of external electrodes. The coil axis of the first coil C1 is arranged inside the second coil C2. The first coil C1 includes a conductor layer 12, a conductor layer 13 and a through-hole conductor 22 which extends in a first direction D1 and connects the conductor layer 12 to the conductor layer 13. The second coil C2 includes a conductor layer 16, a conductor layer 17 and a through-hole conductor 25 which extends in the first direction D1 and connects the conductor layer 16 to the conductor layer 17. The conductor layers 12, 16 are mutually apart in the first direction D1, and mutually intersect when seen from the first direction D1.SELECTED DRAWING: Figure 2 【課題】高周波特性を向上させると共に、インダクタンスを大きく保ちながら、コイルの直流抵抗を低減することができる積層コイル部品を提供する。【解決手段】積層コイル部品1は、素体と、素体内に配置されており、第二方向D2に沿うコイル軸をそれぞれ有している第一コイルC1及び第二コイルC2と、一対の外部電極と、を備える。第一コイルC1のコイル軸は、第二コイルC2の内側に配置されている。第一コイルC1は、導体層12と、導体層13と、第一方向D1に延在し、導体層12と導体層13とを接続しているスルーホール導体22と、を有する。第二コイルC2は、導体層16と、導体層17と、第一方向D1に延在し、導体層16と導体層17とを接続しているスルーホール導体25と、を有する。導体層12及び導体層16は、第一方向D1において互いに離間していると共に、第一方向D1から見て互いに交差している。【選択図】図2
