Abstract: In the wound inductor component, a flange is connected to a first end of a winding core in the central axial line direction, and protrudes from both sides of the winding core along a height direction. A cover member covers a portion from the upper end of the flange to the upper end of the winding core from above. In a sectional view including the central axial line and along the height direction, an area of a first region at an upwardly protruding portion of the flange defined by a boundary between the flange and the winding core, a straight line parallel to the central axial line and passing through the upper end of the flange, and a region surrounded by a portion of the surface of the flange is larger than an area of a similarly defined second region at a downwardly protruding portion of the flange.

Abstract: An inductor component includes a core including a winding core portion, a first collar disposed at a first end of the winding core portion in an axial direction, and a second collar disposed at a second end of the winding core portion in the axial direction. The inductor component further includes a first electrode disposed on the first collar; a second electrode disposed on the second collar; and a wire electrically connected to the first electrode and the second electrode and wound around the winding core portion in such a manner as to form a plurality of wound regions arranged along the axial direction of the winding core portion. A distance between adjacent ones of the wound regions is greater than a winding pitch of the wire in each of the wound regions.

Abstract: A multilayer electronic component includes a multilayer body including insulator layers that are stacked, linear conductor traces each provided between adjacent ones of the insulator layers, and via conductors. A helical or substantially helical inductor is provided in the multilayer body. When viewed in the stacking direction of the multilayer body, all of the linear conductor traces, except a portion of one linear conductor trace, are superimposed within an annular or substantially annular linear conductor trace region. The portion of the one linear conductor trace is displaced inwardly from the annular or substantially annular linear conductor trace region.

Abstract: A wire-wound electronic component includes a core having a winding base extending in an axial direction, a flange provided at an end of the winding base in the axial direction, and a wire wound around the winding base. An external electrode is provided on a plurality of side surfaces of the flange and is connected to an end of the wire, where the side surfaces are orthogonal to the axial direction. A connecting surface on which the end of the wire contacts with the external electrode is one of the side surfaces that is different from one of the side surfaces that functions as a mounting surface, and the external electrode extends from the mounting surface to the end of the wire in such a manner to turn in a direction same as a winding direction of the wire.
