    摘要： A capacitor 1 includes a capacitor element 3 having a predetermined liquid preparation held between a pair of electrodes 5, 7 facing each other across a separator 6, a body case 2 for housing the capacitor element 3, and a sealing member 4 made of rubber for sealing seals the body case 2. A supplying portion is provided in contact with the sealing member 4 to supply the liquid preparation held in the capacitor element 3 to the sealing member 4. The liquid preparation has a lipid-soluble sealing member deterioration preventing agent dissolved in a lipophilic solvent. The sealing member deterioration preventing agent supplied by the supplying portion to the sealing member 4 permeates the sealing member 4. The ratio by weight of the sealing member deterioration preventing agent in the sealing member 4 to the sealing member 4 is 0.1% by weight to 25 % by weight.

    摘要： In a solid electrolytic capacitor having an electrolyte layer consisting of a solid electrolyte layer and a liquid, the solid electrolytic capacitor, which suppresses a dedoping reaction and which ESR thereof does not keenly increase, in particular, after a loading of heat stress, is provided. In the solid electrolytic capacitor, the electrolyte layer is formed in the capacitor element which is formed by opposing an anode foil and a cathode foil. This electrolyte layer includes the solid electrolyte layer and the liquid. The solid electrolyte layer includes a conductive polymer consisting of a dopant and a conjugated polymer. The liquid is filled in air gaps in the capacitor element on which the solid electrolyte layer is formed. The electrolyte layer includes ammonia as a cation component, and a molecular ratio of the cation component relative to 1 mol of a functional group which can contribute to a doping reaction of the dopant, in the electrolyte layer is 23 or less.
