1. A passive component comprising:
a substrate having insulating properties and having an upper surface having a recess;
a bottom electrode filling at least a portion of the recess;
a dielectric film on an upper surface of the bottom electrode; and
a top electrode opposite to the bottom electrode with the dielectric film interposed therebetween, wherein,
in a height direction perpendicular to the upper surface of the substrate, a dimension of the bottom electrode is larger than a dimension of the dielectric film,
the bottom electrode protrudes above the upper surface of the substrate,
entire sides of a portion of the bottom electrode positioned above the upper surface of the substrate and the upper surface of the bottom electrode are covered with only one material, and
the substrate has a first interface configured of materials that are different and are in contact with one another in a thickness direction of the substrate, and the recess is recessed from the surface of the substrate and reaches the first interface.
