Abstract
A coil component comprising a core having a winding core part, and a coil wound around the winding core part and including a plurality of wires. The coil includes a twisted wire portion in which the plurality of wires is twisted together. The twisted wire portion includes a bank region including a first layer wound multiple turns continuously around the winding core part and a second layer wound on the first layer continuously from the first layer. The bank region is sparsely wound with the number of turns of the second layer reduced by two or more as compared to the number of turns of the first layer.
