| 摘要 |
A capacitor and a manufacturing method thereof with improved capacitance density, simplified production process, and/or improved high frequency characteristic without having to form a nano-scale pattern are provided. A capacitor element 12 includes a dielectric layer made of porous oxide substrate, first and second internal electrodes formed within holes of the porous oxide substrate, a first external electrode electrically connected to the first internal electrode, a second external electrode electrically connected to the second internal electrodes.
