Abstract
An electronic component includes first and second filter circuits. The first filter circuit has a first inductor on a first conductor layer. The second filter circuit has a second inductor on a second conductor layer and a third inductor on a third conductor layer. These inductors are aligned side by side in a direction orthogonal to the stacking direction of the conductor layers. The third conductor layer is at the same vertical position as parts of the first and second conductor layers. The first and second conductor layers each have more layers than the third conductor layer.

An electronic component comprising:
- an element body including a plurality of insulating layers and a plurality of conductor layers, the plurality of insulating layers and the plurality of conductor layers being stacked;
- a plurality of terminals disposed on the element body;
- a first filter circuit including at least one or more conductor layers of the plurality of conductor layers and configured to process a signal in a first frequency band;
- and
- a second filter circuit including at least one or more conductor layers of the plurality of conductor layers and configured to process a signal in a second frequency band higher than the first frequency band, wherein
- the first filter circuit includes a first inductor formed by winding on a first conductor layer including two or more conductor layers of the plurality of conductor layers,
- the second filter circuit includes
- a second inductor formed by winding on a second conductor layer including two or more conductor layers of the plurality of conductor layers, and
- a third inductor formed by winding on a third conductor layer including one or more conductor layers of the plurality of conductor layers,
- the first inductor, the second inductor, and the third inductor are disposed side by side in a first direction orthogonal to a stacking direction in which the plurality of conductor layers is stacked in a plan view viewed in the stacking direction,
- the third conductor layer is positioned at an identical vertical position to a part of the first conductor layer and a part of the second conductor layer in the stacking direction, and
- each of a number of conductor layers of the plurality of conductor layers constituting the first conductor layer and a number of conductor layers of the plurality of conductor layers constituting the second conductor layer is larger than a number of conductor layers of the plurality of conductor layers constituting the third conductor layer.
