Abstract

Provided is a multilayer coil component in which a position of a boundary between a first portion and a third portion in a second wiring portion located closer to a side surface is located closer to an end surface in a first direction than a position of a boundary between a first portion and a third portion in a second wiring portion located closer to a side surface, and a position of a boundary between a second portion and a third portion in a second wiring portion located closer to the side surface is located closer to an end surface in the first direction than a position of a boundary between a second portion and a third portion in a second wiring portion located closer to the side surface.

Dependent claims

A multilayer coil component comprising:

an element body that includes a pair of end surfaces opposite each other in a first direction, a mounting surface and a main surface opposite each other in a second direction, and a pair of side surfaces opposite each other in a third direction;
a pair of terminal electrodes disposed on the mounting surface of the element body;
a coil that is disposed in the element body and electrically connected to the pair of terminal electrodes;
and
a first connecting conductor connecting one end portion of the coil to one terminal electrode and a second connecting conductor connecting the other end portion of the coil to the other terminal electrode,
wherein the first connecting conductor is disposed closer to one end surface and closer to the other side surface,
the second connecting conductor is disposed closer to the other end surface and closer to one side surface,
the coil includes a plurality of first wiring portions disposed on the main surface side, a plurality of second wiring portions disposed on the mounting surface side, and a plurality of connecting portions that extend in the second direction and connect the first wiring portions to the second wiring portions,
when viewed in the second direction, each of the plurality of second wiring portions includes:
a first portion that includes a region overlapping the corresponding connecting portion and is located closer to the one end surface;
a second portion that includes a region overlapping the corresponding connecting portion and is located closer to the other end surface;
and
a third portion that connects the first portion to the second portion and is inclined with respect to the first direction,
in the adjacent second wiring portions, when viewed in the second direction,
a position of a boundary between the first portion and the third portion in the second wiring portion located closer to the one side surface is located closer to the other end surface in the first direction than a position of a boundary between the first portion and the third portion in the second wiring portion located closer to the other side surface, and
a position of a boundary between the second portion and the third portion in the second wiring portion located closer to the other side surface is located closer to the one end surface in the first direction than a position of a boundary between the second portion and the third portion in the second wiring portion located closer to the one side surface.
