发明名称 MULTILAYER COIL
摘要 A coil is provided at a multilayer body including insulating layers stacked on one another. The coil includes linear conductors connected by via conductors to make a looped track when viewed from a layer stacking direction. The linear conductors include a first linear conductor contacting with an external electrode provided on the surface of the multilayer body, and a second linear conductor forming a half of the looped track. The first linear conductor includes a coil portion forming a part of the looped track. The second linear conductor is adjacent to the first linear conductor with one of the insulating layers in-between, and a first end of the second linear conductor is connected to a first end of the first linear conductor by a first via conductor. A second end of the second linear conductor does not overlap the first linear conductor when viewed from the layer stacking direction.

主权项 1. A multilayer coil comprising: a multilayer body including a plurality of insulating layers stacked on one another; a coil provided at the multilayer body and including a plurality of linear conductors connected together by a plurality of via conductors piercing through the insulating layers; and a first external electrode provided on a surface of the multilayer body, wherein: the coil makes a looped track when viewed from a layer stacking direction in which the plurality of insulating layers are stacked; the plurality of linear conductors includes a first linear conductor contacting with the first external electrode, and a second linear conductor forming a part of the looped track when viewed from the layer stacking direction and having a length corresponding to a half turn of the looped track; at least a part of the first linear conductor is a coil portion forming a part of the looped track when viewed from the layer stacking direction; the second linear conductor is adjacent to the first linear conductor with at least one of the insulating layers in-between, and a first end of the second linear conductor is connected to a first end of the first linear conductor by a first via conductor of the plurality of via conductors; and a second end of the second linear conductor adjacent to the first linear conductor with the at least one insulating layer in-between does not overlap the first linear conductor when viewed from the layer stacking direction.
