Electrolytic capacitor and electrode foil used for electrolytic capacitor |
摘要 |
There are provided a solid electrolytic capacitor having a low ESR characteristic and an electrode foil to be used for this electrolytic capacitor. In accordance with the present invention, a capacitor element uses an anode foil with a post-etching void factor of not more than 51% or a cathode foil with another post-etching void factor of not more than 44%, wherein the capacitor element contains a solvent consisting mainly of a water and a water-soluble metal complex being bonded with phosphoric acid ions, whereby the electrode foil increases in conductivity and decreases in resistivity, while an electrolytic solution thereof has a low resistivity, to thereby obtain the solid electrolytic capacitor having the low ESR characteristic and the electrode foil to be used therefor.
