Abstract
An electronic component includes: a conductive pattern provided on the main surface of a substrate and constituting a lower electrode; a dielectric film that covers top and side surfaces of the conductive pattern; and a conductive pattern stacked on the top surface of the conductive pattern through the dielectric film and constituting an upper electrode. A part of the dielectric film that is parallel to the main surface of the substrate is removed at least partly. Partially removing a part of the dielectric film that is parallel to the main surface of the substrate allows stress relaxation. This prevents peeling at the interface between the lower electrode and the dielectric film.
