Zusammenfassung:To provide a coil component that has a coil portion with improved delamination defects and improved rigidity, minimizes the reduction in effective volume while improving the rigidity of the coil portion, improves the adhesion strength between the coil portion and the external electrode, and prevents board warpage.SOLUTION: A coil component 1000 includes a main body 100, a coil portion 300 disposed within the main body and including a coil pattern 312 having a plurality of turns and a pull-out portion 332 extending to one side of the main body, and an external electrode placed on the main body and connected to the pull-out portion. The outermost turn of the coil pattern 312 has a first region 312s and a second region 312c, the line width of the second region is larger than the line width of the first region, and the line width of the second region is greater than the line width of the turn most adjacent to the outermost turn.SELECTED DRAWING: Figure 2 【課題】デラミネーション不良が改善され、剛性が向上したコイル部を有し、コイル部の剛性が改善されながらも有効体積の減少が最小化し、コイル部と外部電極との間の固着強度が改善され、基板の反り(warpage)が防止されるコイル部品を提供する。【解決手段】コイル部品1000は、本体100、本体内に配置され、複数のターンを有するコイルパターン312及び本体の一側面に延びた引き出し部332を含むコイル部300及び本体に配置されて引き出し部と連結された外部電極を含む。コイルパターン312の最外側ターンは、第1領域312s及び第2領域312cを有し、第2領域の線幅は第1領域の線幅よりも大きく、第2領域の線幅は、最外側ターンと最も隣接したターンの線幅よりも大きい。【選択図】図2
