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.
