ABSTRACT:
An electrolytic capacitor having a low impedance characteristic, having a high withstand voltage characteristic of 100V class, wherein the electrolytic capacitor provides an excellent high temperature life characteristic.The electrolyte solution containing the aluminum tetrafluoride salt is used. The moisture content of the capacitor element is adjusted to 0.7% by weight or less, wit respect to the weight of the capacitor element, preferably 0.5% by weight or less, and most preferably 0.4% by weight or less. In this way, the electrolytic capacitor having the low impedance characteristic and the high resistance voltage characteristic, and the excellent high temperature life characteristic is provided.
