Abstract
A capacitor that includes a conductive porous substrate having a porous portion; a dielectric layer on the porous portion and containing an oxygen element and at least metal element; and an upper electrode on the dielectric layer. The porous portion has a path integral value of 1 μm/μmto 16 μm/μm, and a porosity of 20% to 90%, and a ratio Z expressed by (1) below is 0.79 or more, where Oand Mrespectively represent signal intensities of the oxygen element and the metal element when the dielectric layer is analyzed by energy dispersive X-ray spectroscopy (EDS), and where Oand Mrespectively represent signal intensities of the oxygen element and the metal element when a reference material having stoichiometric composition of the oxygen element and the at least one metal element constituting the dielectric layer is analyzed by the EDS.
