Abstract: A surface mount inductor includes a coil including a wound portion and a feeder end portion drawn out from the wound portion, a compact that contains a magnetic powder and that encapsulates the coil, and an external terminal disposed on the compact and connected to the coil. The compact has surfaces including two pressed surfaces, opposing each other in a direction of an axis of the wound portion and formed by being pressed in the direction of the axis, and a non-pressed surface, adjacent to the two surfaces and not pressed. The coil is disposed so that the axis of the wound portion is parallel to a mount surface of the compact. The mount surface is included in the non-pressed surface, the feeder end portion is exposed from the mount surface, and the external terminal is formed on only the non-pressed surface and connected to the feeder end portion.

Abstract: An inductor that includes a body having a magnetic portion containing a magnetic powder and a first resin; a coil that is encapsulated in the body and includes a winding portion formed by winding a conductor and a pair of lead-out portions that extend from the winding portion; and a pair of outer electrodes to which at least end portions of the lead-out portions are connected at surfaces of the body. The outer electrodes each includes an electrically conductive resin layer and a first cover layer arranged on the electrically conductive resin layer. The electrically conductive resin layers each contain an electrically conductive powder and a second resin and a plurality of electrically conductive metal portions composed of the same material as the first cover layers are contained inside the electrically conductive resin layers.

Abstract: An inductor includes a coil having a winding portion of a conductor wound in a two-stage spiral shape and an extended portion extended from the winding portion, an element body containing the coil, and an outer electrode. The winding portion is arranged such that a winding axis intersects a first pair of surfaces, is substantially orthogonal to the first pair of surfaces as viewed from a second pair of surface side, and intersects a normal line on the first pair of surfaces as viewed from a third pair of surfaces side. Respective pairs of surfaces are opposed to one another, and the winding axis is inclined in a direction where an exposed portion exposed on a surface of the element body is positioned closer to an intermediate surface at an equal distance from respective first pair of surfaces relative to the normal line on the first pair of surfaces.
