Abstract
A capacitor includes: a capacitor element; an electrolyte impregnated into at least the capacitor element; a bottomed cylindrical metal case accommodating the capacitor element and the electrolyte; and a sealing body sealing an opening portion of the case. Further, the capacitor also includes a coating layer provided at a portion in contact with the outer surface of the sealing body and formed by dispersing, into resin, an adsorbent adsorbing a solvent included in the electrolyte. Alternatively, the sealing body is formed by dispersing the above-described adsorbent in a rubber component.
