Summary:The invention provides a coil component. In a common mode choking coil as an example of the coil component, excellent model conversion characteristics can be guaranteed even the number of turns of wires is increased for obtaining high inductance. A wire assembly portion (44) formed by twisting two wires is wrapped around a winding core portion (45). The wire assembly portion (44) comprises an inner layer portion (N) that is in contact with and wound around the circumferential surface of the winding core portion with a first end portion (46) as the initial end, an outer layer portion (G) wound around the outer circumference of the inner layer portion, outward transition portions each extending from the inner layer portion to the outer layer portion, and an inward transition portion extending from the outer layer portion to the inner layer portion. The wire assembly portion is lead out from the middle position in the winding center axis direction of the inner layer portion by means of the outward transition por
