PROBLEM TO BE SOLVED: To prevent occurrence of crack.SOLUTION: A layered coil component comprises: a magnetic element assembly 2: and a coil 20 disposed in the element assembly 2 and including coil conductors 21 to 23 having annular parts 21A, 22A, 23A and extended parts 21B, 22B, 23B. The coil conductor 22 is located between the coil conductors 21 and 23 in a Z direction. As viewed from the Z direction, the conductor parts 21a, 23a of the coil conductors 21, 23 comprise first portions 21g, 23g superposed on the edges 21a, 21dof the coil conductor 22, adjacent in the Z direction; and second portions 21f, 23f superposed on the separate portion between the edges 21a, 21dof the coil conductor 22, adjacent in the Z direction. The second portions 21f, 23f recede opposite the separate portion between the edges 21a, 21dof the coil conductor 22, compared to the first portions 21g, 23g.SELECTED DRAWING: Figure 7 【課題】クラックの発生を抑制する。【解決手段】磁性を有する素体２と、素体２内に配置されていると共に、環状部２１Ａ，２２Ａ，２３Ａと、延在部２１Ｂ，２２Ｂ，２３Ｂと、をそれぞれ有しているコイル導体２１〜２３を含むコイル２０と、を備え、コイル導体２２は、Ｚ方向でコイル導体２１，２３の間に位置しており、コイル導体２１，２３の導体部２１ａ，２３ａは、Ｚ方向から見て、Ｚ方向で隣り合っているコイル導体２２の各縁２１ａ１，２１ｄ１に重なっている第一部分２１ｇ，２３ｇと、Ｚ方向で隣り合っているコイル導体２２の各縁２１ａ１，２１ｄ１の間の離間部分に重なっている第二部分２１ｆ，２３ｆと、を有し、第二部分２１ｆ，２３ｆは、第一部分２１ｇ，２３ｇに比べて、コイル導体２２の各縁２１ａ１，２１ｄ１の間の離間部分と反対側に窪んでいる。【選択図】図７
