Coil component

A coil component comprising:

• a bar-like core not including a flange part;
• and
• a winding part formed of a conducting wire that is wound in a plurality of layers around a longitudinal outer periphery of the core according to a solenoidal winding method while being turned back sequentially from a lower layer to an upper layer,
• the coil component further comprising a winding collapse preventing shift corresponding to a plurality of turns between an end part of a lower winding layer and an end part of an upper winding layer, the winding collapse preventing shift being set to each end part in a winding width direction of each winding layer of the winding part, wherein
• in a case of transition from the lower winding layer to the upper winding layer, the conducting wire is turned back from the end part of the lower winding layer, and is obliquely wound in a small number of turns across the winding collapse preventing shift corresponding to the plurality of turns, and dense winding of the upper winding layer is started.
