Abstract

An electronic component includes a first main body and a second main body. The second main body is mounted on a first surface of the first main body. The first main body includes a first region that overlaps the second main body when viewed in a stacking direction, and a second region that does not overlap the second main body when viewed in the stacking direction. At least a part of the plurality of capacitor conductors is disposed in the first region. At least one inductor conductor includes a major part disposed in the second region, and a non-major part. The non-major part is disposed in the second region, or is disposed at least in part in the first region.

2 . The electronic component according to claim 1 , wherein the first circuit includes the at least one capacitor and the at least one inductor.

3 . The electronic component according to claim 1 , wherein no other inductors and no other capacitors are provided between the at least a part of the plurality of capacitor conductors and the second main body.

4 . The electronic component according to claim 1 , wherein
an area of a planar figure created by vertically projecting the at least a part of the plurality of capacitor conductors, the at least a part being disposed in the first region, onto the first surface is greater than an area of a planar figure created by vertically projecting a part of the non-major part, the part being disposed in the first region, onto the first surface.

5 . The electronic component according to claim 1 , wherein
the at least one capacitor comprises a plurality of capacitors, and the at least a part of the plurality of capacitor conductors, the at least a part being disposed in the first region, constitutes two or more of the plurality of capacitors.
