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.
