Patent ID: 8112872

Claim:
A method of producing a coil component comprising a core having a winding portion, a pair of flanges having an outer peripheral surface and providing a winding accommodating region defined by the winding portion and the pair of flanges; terminal electrodes disposed on at least one of the pair of flanges; and a winding wound about the winding portion and connected to the terminal electrodes; the method comprising: wrapping the winding about the winding portion in layers within the winding accommodating region to provide a wound portion; connecting ends of the winding to the terminal electrodes; and immersing a portion of the outer peripheral surface, less than a whole of the outer peripheral surface, of the pair of flanges in a liquid resin bath to permit the liquid resin to penetrate the winding accommodating region between the pair of flanges by a capillary effect to form a resin coating over an entire outer peripheral surface of the winding portion of the winding within the winding accommodating region, and simultaneously forming a marker made from the liquid resin on the immersed portion of the outer peripheral surface, wherein the immersing causes the liquid resin to rise in a direction opposing the liquid resin bath to penetrate the winding accommodating region between the pair of flanges due to the capillary effect, and the liquid resin only penetrates the winding accommodating region between the pair of flanges.
