Abstract
Official abstract text for this publication.
A coil component includes: a bar-like core; and a winding part formed of a conducting wire that is wound in a plurality of layers around the outer periphery of the core according to a solenoidal winding method. Winding collapse preventing shifts D 1 to D 4 each corresponding to a plurality of turns between an end part of a lower winding layer and an end part of an upper winding layer are respectively set to both end parts in the winding width direction of winding layers of the winding part. In transitioning 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 each winding collapse preventing shift corresponding to the plurality of turns, and dense winding of the upper winding layer is started.
First claim
Opening claim text (preview).
What is claimed is: 1. 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 being provided with a winding collapse preventing shift part comprising a space corresponding to a plural…
