    Abstract: A coil component has a magnetic body of rectangular solid shape, a coil with N turns (N is a positive number of 2 or greater) provided inside the magnetic body, an insulating intermediate part, and external electrodes. The coil has a first conductor layer, a second conductor layer, and an inter-layer connection part. The first conductor layer has a first multiple winding part which is wound around one axis with a first spacing. The second conductor layer has a second multiple winding part which is wound around the one axis with the first spacing and faces the first conductor layer. The insulating intermediate part is provided inside the magnetic body and forms, between the first conductor layer and second conductor layer, a second spacing corresponding to a thickness equal to or less than the product of the first spacing and (N−1).

    Abstract: A magnetic body is constituted by grains of a soft magnetic alloy bonded together via an oxide layer, wherein: the soft magnetic alloy is an alloy containing Si by 1 to 5.5 percent by mass, and Cr and/or Al by 0.2 to 4 percent by mass in total, as constituent elements, with Fe and unavoidable impurities accounting for the remainder, wherein a content of Si is more than a content of Cr and Al in total; and the oxide layer contains Si, as well as at least one of Fe, Cr, and Al, where, among Fe, Si, Cr, and Al, Si is contained in the largest quantity based on mass. The magnetic body can have high magnetic permeability.

    Abstract: A coil component comprises a coil conductor including a circling portion extending around a coil axis, a base body covering the circling portion, a first external electrode, and a second external electrode. The base body has a first surface intersecting the coil axis, a second surface opposite to the first surface, and an outer surface including a connecting surface connecting the first surface with the second surface. The outer surface of the base body includes a main body portion and at least one high resistance portion. The high resistance portion occupies an area of the connecting surface between the first external electrode and the second external electrode, other than the part occupied by the main body portion. The area extends along an entire length of a circumference of the base body around the coil axis. The high resistance portion has a higher volume resistivity than the main body portion.
