Abstract

One object is to provide a porous capacitor having an improved mechanical strength and a method of manufacturing the porous capacitor. In accordance with one aspect, the porous capacitor has a first conductor layer a second conductor layer opposed to each other at a certain distance, a dielectric layer made of an oxidized valve metal and disposed between the first conductor layer and the second conductor layer, a large number of holes in the dielectric layer substantially orthogonal to the first conductor layer and the second conductor layer, first and second electrodes made of a conductive material filled in the holes, insulators for electrically insulating the first electrodes from the second conductor layer and the second electrodes from the first conductor layer, wherein the levels of the ends of the first and/or second electrodes electrically insulated from the second and/or first conductor layers are uneven with each other.
