  • Publication number: 20240203625
    Abstract: To suppress an increase in DC resistance due to surface roughening in a coil component including a spiral pattern. A coil component manufacturing method includes: a first step of forming a conductor layer including a spiral pattern spirally wound in a plurality of turns; a second step of selectively roughening an upper surface and an upper region of a peripheral-direction side surface of the spiral pattern; and a third step of forming an insulating resin layer so as to embed therein the conductor layer, and the first to third steps are repeatedly performed. Since the upper surface and the upper region of the side surface of the spiral pattern are selectively roughened, it is possible to suppress an increase in DC resistance due to excessive roughening at the lower region of the side surface.
