Summary: | To provide a coil component that can secure connection reliability between a coil and external electrodes while suppressing increase in the number of manufacturing steps and increase in time and effort.SOLUTION: A coil component 1, 1A, 1B comprises an element body 2, a coil 3, metal wires 4 and 5, and external electrodes 6 and 7. The coil 3 is arranged in the element body 2. The coil 3 has tips 3a and 3b exposed from the element body 2. The metal wires 4 and 5 are connected with the tips 3a and 3b, respectively. The metal wires 4 and 5 extend along an outer surface of the element body 2, on the outer surface. The external electrodes 6 and 7 are connected with the metal wires 4 and 5 outside the element body 2, respectively. The external electrodes 6 and 7 are electrically connected with the coil 3 via the metal wires 4 and 5, respectively. A contact area of the external electrodes 6 and 7 with the metal wires 4 and 5 is larger than a cross-sectional area at the tips 3a and 3b of the coil 3.SELECTED DRAWING: Figure 1
【課題】製造の工程数及び手間の増加が抑制されながら、コイルと外部電極との接続の信頼性が確保され得るコイル部品を提供する。【解決手段】コイル部品1,1A,1Bは、素体2と、コイル3と、金属線4,5と、外部電極6,7とを備えている。コイル3は、素体2の内部に配置されている。コイル3は、素体2から露出している先端3a,3bを有している。金属線4,5は、上記先端3a,3bに接続されている。金属線4,5は、素体2の外表面上において外表面に沿って延在している。外部電極6,7は、素体2の外部において金属線4,5に接続されている。外部電極6,7は、金属線4,5を介してコイル3に電気的に接続されている。外部電極6,7と金属線4,5との接触面積は、コイル3の先端3a,3bにおける断面積よりも大きい。【選択図】図1 |
