Abstract

This invention is to provide a coil component in which a height is lowered and the deterioration of magnetic characteristics can be suppressed, and to provide its manufacturing method. The coil component 1 is provided with a core 13, a winding wire 21, an internal electrode layer 23, an exterior resin 25, and an external electrode layer 11. The core 13 is provided with a winding core 15 and a pair of flanges 17, and the winding wire 21 is wound around the winding core 15. The internal electrode layer 23 is formed so as to cover the end face 17a and peripheral side face 17b of the flange 17 and the end of the winding wire 21 is connected. The exterior resin 25 is formed so as to cover the winding wire 21 and a part formed on the peripheral side face 17b of the internal electrode layer 23. The external electrode layer 11 includes a lower layer electrode layer 11a and an upper layer electrode layer 11b. The lower layer electrode layer 11a is formed so as to cover the exposed part of the internal electrode layer 23, and the end of the exterior resin part 25. The upper layer electrode layer 11b is formed so as to cover the exposed part of the lower layer electrode layer 11a.
