To provide an inductor component capable of suppressing occurrence of crack caused by a stress residual in the vicinity of a lead-out wire in a manufacturing process.SOLUTION: An inductor component 1A comprises: an element assembly 10; a coil 20 provided in the element assembly 10 and spirally wound in a coil axis direction; a first external electrode 30a electrically connected to one end of the coil 20 and exposed on a surface of the element assembly 10; and a second external electrode 30b electrically connected to the other end of the coil 20 and exposed on the surface of the element assembly 10. The element assembly 10 includes an insulator, and the coil 20 is configured by electrically connecting a plurality of coil wires laminated in the coil axis direction. The plurality of coil wires includes a first coil wire 21a which is electrically connected to the first external electrode 30a via at least one first lead-out wire 22aa. A dimension of each first lead-out wire 22aa in the coil axis direction is smaller than a dimension of the first coil wire 21a in the coil axis direction.SELECTED DRAWING: Figure 1 【課題】製造過程において引出配線の近傍に残留する応力に起因するクラックの発生を抑制することが可能なインダクタ部品を提供する。【解決手段】素体１０と、素体１０の内部に設けられ、かつ、コイル軸方向に沿って螺旋状に巻回されたコイル２０と、コイル２０の一方端部に電気的に接続され、かつ、素体１０の表面に露出した第１外部電極３０ａと、コイル２０の他方端部に電気的に接続され、かつ、素体１０の表面に露出した第２外部電極３０ｂと、を備え、素体１０は、絶縁体を含み、コイル２０は、コイル軸方向に積層された複数のコイル配線が電気的に接続されてなり、複数のコイル配線は、少なくとも１つの第１引出配線２２ａａを介して第１外部電極３０ａに電気的に接続された第１コイル配線２１ａを含み、各々の第１引出配線２２ａａのコイル軸方向における寸法は、第１コイル配線２１ａのコイル軸方向における寸法よりも小さい、インダクタ部品１Ａ。【選択図】図１
