A method of manufacturing a coil component includes arranging a plurality of coil conductors that is a wound body of a conductive wire, and each has opposing first and second surfaces, in a winding axis direction on a surface of an adhesive layer in contact with the first surface, manufacturing a processed body by placing a first magnetic sheet including a first metal magnetic particle and a first resin on a side of the second surface of each of the coil conductors and performing press processing on the first magnetic sheet, manufacturing an aggregate base body by peeling the processed body from the adhesive layer, placing a second magnetic sheet including a second metal magnetic particle and a second resin on a side of the first surface of each coil conductor, and press processing the second magnetic sheet, and manufacturing a body by individualizing the aggregate base body.
