Abstract
Provided is a solid electrolyte capacitor which includes: a bottomed cylindrical housing which includes a bottom surface portion and a side surface portion raised from the bottom surface portion, and has an opening portion formed on an edge portion of the side surface portion; a capacitor element which is accommodated in the inside of the housing, and is formed by winding an anode foil and a cathode foil in an overlapping state with a separator interposed therebetween and by filling a space formed between the anode foil and the cathode foil with a solid electrolyte; a sealing member which seals the opening portion of the housing in a state where the capacitor element is accommodated in the inside of the housing; and a composite sheet which is arranged between the bottom surface portion of the housing and the capacitor element, and has the structure where a resin made of a high-molecular weight compound is retained in a fiber sheet containing at least cellulose fibers.
