Abstract
One object is to provide a porous capacitor having increased insulation reliability. In accordance with one aspect, the porous capacitor includes: a first conductor layer and a second conductor layer opposed to each other at a predetermined 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 formed through the dielectric layer and oriented substantially orthogonal to the first conductor layer and the second conductor layer; and first electrodes and second electrodes formed of a conductive material filled in the holes; and insulation parts insulating the first electrodes from the second conductor layer and insulating the second electrodes from the first conductor layer. The thicknesses of the first conductor layer and the second conductor layer are equal to or greater than half of the inner diameter of the holes.
