A method of manufacturing an inductor includes a lamination step, a division step, a firing step, and a plating step. In the lamination step, a laminate including an insulator, a coil body, and external electrodes is formed. That is, in the lamination step, insulating layers having wide filling conductors, insulating layers having narrow filling conductors, and conductor patterns having external electrode patterns are laminated. As a result, the conductor patterns form the coil body, and the wide filling conductors, the narrow filling conductors, and the external electrode patterns form the external electrodes. The narrow filling conductors have a width that is less than the widths of the wide filling conductors and the external electrode patterns, and recesses and projections are provided in the external electrodes.
