1. 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, wherein
the coil includes a twisted wire portion in which the plurality of wires is twisted together,
the twisted wire portion includes a plurality of bank regions arranged along the winding core part in an axial direction of the winding core part, each of the bank regions 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, and
a bank region from among the plurality of bank regions arranged closest to a terminal end of the winding core part is a closely-wound bank region having a number of turns of the second layer reduced by one as compared to a number of turns of the first layer,
all the bank regions except for the closely-wound bank region are sparsely wound with a number of turns of the second layer reduced by two or more as compared to a number of turns of the first layer.
