Abstract
A coil component including a first conductive plate part formed with a first coil pattern having a first opening, and a second conductive plate part formed with a second coil pattern having a second opening and disposed at a predetermined interval in the laminating direction with respect to the first conductive plate part. The first conductive plate part and the second conductive plate part are made of the same single plate and are integrally formed by a bent joining segment.
