Abstract
A coil component is provided which includes a pot core having a bottom in which through holes are formed, a composite coil retained in the pot core, and a cover core joined to the rim of the pot core. The coil has terminals inserted in the through holes to such an extent that the lower ends thereof do not protrude beyond the bottom, the bottom having membrane external electrodes formed on the outer surface thereof and connected with the terminals. The composite coil comprises an inner coil wound around an inner leg of the pot core and an outer coil wound around the inner coil with a gap formed between the inner and outer coils so as to make larger the length of the outer coil than the case where the outer coil is directly wound around the inner coil.
