| 摘要 |
The present invention provides an electrolytic capacitor which uses, as an anode body thereof, a sintered body that is obtained by sintering a tungsten powder containing zirconium element and/or hafnium element so that the content of one of these elements, which is contained in a larger amount, is 0.04 to 1 mass % and the element(s) is localized in the surface of tungsten particles. The electrolytic capacitor of the present invention has a large capacitance and good LC characteristics, while being suppressed in capacitance variation. |
