    Abstract: A capacitor that includes a substrate having a first principal surface, a second principal surface facing the first principal surface, and a first end surface connecting the first principal surface and the second principal surface, a lower electrode on the first principal surface of the substrate, a dielectric film on the lower electrode, an upper electrode on the dielectric film, a protective film covering the upper electrode and having a thickness smaller than that of the substrate, and a first terminal electrode on the first end surface and electrically connected to one of the upper electrode and the lower electrode.

    Abstract: A capacitor that prevents generation of a substrate capacitance composed of an upper electrode, a substrate, and a lower electrode. Specifically, the capacitor includes a substrate; a lower electrode disposed on the substrate; a dielectric film disposed on the lower electrode; an upper electrode disposed on a part of the dielectric film; and a first terminal electrode that is connected to the upper electrode. Moreover, the upper electrode and the first terminal electrode are formed in a region for forming the lower electrode in a plan view of the capacitor viewed from the first terminal electrode side.

    Abstract: A capacitor that includes a substrate; a lower electrode formed on the substrate, and including an upper surface, a lower surface and an end surface that connects the upper surface and the lower surface. Moreover, the capacitor includes a dielectric film formed on the lower electrode; an upper electrode formed on the dielectric film; and a terminal electrode connected to the upper electrode. Furthermore, the upper surface of the lower electrode is formed in a region on an inner side of a periphery of the lower surface of the lower electrode with at least part of the end surface being a tapered shape.
