To provide an inductor component which can prevent degradation in strength of an element body and reduction in inductance while preventing a short-circuit between itself and another electronic component.SOLUTION: An inductor component comprises: an element body which contains magnetic particles, and which has a first principal surface, a second principal surface, and a lateral surface connecting the first principal surface to the second principal surface; inductor wiring provided inside the element body; first vertical wiring, provided inside the element body, which is connected to a first end of the inductor wiring and extends to the first principal surface; second vertical wiring, provided inside the element body, which is connected to a second end of the inductor wiring and extends to the first principal surface; a first external terminal which is connected to the first vertical wiring and is exposed on the first principal surface; and a second external terminal which is connected to the second vertical wiring and is exposed on the first principal surface. The magnetic particles are mainly composed of an Fe element. The lateral surface has: an oxidized region where an oxide film made up of a plurality of oxidized magnetic particles is exposed; and a non-oxidized region where a plurality of magnetic particles are exposed.SELECTED DRAWING: Figure 1 【課題】他の電子部品とのショートを抑制しつつ、素体強度の低下およびインダクタンスの低下を抑制することができるインダクタ部品を提供する。【解決手段】インダクタ部品は、磁性粉を含み、第１主面および第２主面と、第１主面と第２主面とを接続する側面と、を有する素体と、素体内に設けられたインダクタ配線と、素体内に設けられ、インダクタ配線の第１端部に接続され第１主面まで延在する第１垂直配線と、素体内に設けられ、インダクタ配線の第２端部に接続され第１主面まで延在する第２垂直配線と、第１垂直配線に接続され、第１主面において露出する第１外部端子と、第２垂直配線に接続され、第１主面において露出する第２外部端子とを備え、磁性粉は、Ｆｅ元素を主成分とし、側面は、複数の磁性粉が酸化された酸化膜が露出している酸化領域と、複数の磁性粉が露出している非酸化領域とを有する。【選択図】図１
