Zusammenfassung:The invention provides a coil component which has excellent magnetic characteristics and contributes to improvement of yield, and a method for manufacturing the coil component. A coil component (1) is provided with: a coil (10); a substantially T-shaped core (20) having a winding core portion (21) around which the coil (10) is disposed, and a flange portion (22) formed at a first end (21a) of the winding core portion (21) in the axial direction; and an exterior body (30) which is formed from an exterior material containing magnetic particles and a resin and seals the coil (10) together with the winding core part (21). A recess (40) having at least one of a first recess (41) and a second recess (42) is formed on the surface of the core (20). The first recessed portion (41) extends from a second end (21b) of the winding core portion (21) in the axial direction toward the first end (21a), and the second recessed portion (42) extends from the inner side of the flange portion (22) toward the outer side. 本发明提供一种磁特性
