Abstract
To prevent interfacial peeling due to the stress of an insulating layer in a capacitor-inductor integrated electronic component having three or more conductor layers. An electronic component includes: a conductor layer Mincluding a conductor pattern constituting an inductor; a conductor pattern overlapping a part of the conductor pattern through a dielectric film; an insulating layer covering the conductor layer Mand conductor pattern; a conductor layer Mprovided on the insulating layer and including a conductor pattern constituting the inductor; and an insulating layer covering the conductor layer M. The conductor layer Mis formed to be branching from or independently of the conductor pattern and further includes a dummy pattern overlapping the conductor pattern. This prevents the stress of the insulating layer from being directly applied to the conductor pattern to thereby prevent peeling at the interface between the conductor layer Mand the dielectric film.
