ABSTRACT:
A capacitor includes a first capacitor element and a second capacitor element laminated on this first capacitor element. The first capacitor element is a solid electrolytic capacitor including a through-hole electrode penetrating a valve metal sheet and having one surface on which cathode and anode terminal portions are taken out. The second capacitor element has first and second electrodes which are provided via a dielectric layer, and second through-hole electrodes penetrating the dielectric layer. The second through-hole electrodes are coupled to the first electrode and insulated from the second electrode. Lead-out portions of the second electrodes are exposed from the dielectric layer. The second through-hole electrodes and the lead-out portions are disposed alternately. The first electrode is electrically coupled to the first through-hole electrode and the second electrode is electrically coupled to the valve metal sheet.
