Beschreibung
Zusammenfassung:	A directional coupler includes a multilayer body including a plurality of stacked dielectric layers, a main line including a first main line portion and a second main line portion which are connected in series to each other in this order and that is provided in the multilayer body, and a sub-line including a first sub-line portion and a second sub-line portion which are connected in series to each other in this order, the first sub-line portion being electromagnetically coupled to the first main line portion, the second sub-line portion being electromagnetically coupled to the second main line portion, and the sub-line being provided on one side in a stacking direction with respect to the main line in the multilayer body. The second main line portion is provided on a dielectric layer that is different from a dielectric layer on which the first main line portion is provided and/or the second sub-line portion is provided on a dielectric layer that is different from a dielectric layer on which the first sub-line portion is provided.
