▎ 摘  要

NOVELTY - Solid electrolyte capacitor (C1) comprises: a sintered body (110) containing metal; and a conductive polymer layer (130) disposed on the sintered body, where a ratio (t2/t1) of a thickness (t2) of the conductive polymer layer in an edge portion of the sintered body to a thickness (t1) of the conductive polymer layer in a central portion of the sintered body satisfies 0.35 less than or equal to t2/t1 less than or equal toless than or equal to 0.9. USE - Used as solid electrolyte capacitor. ADVANTAGE - The capacitor utilizes conductive polymer layer may include carbon black, thus increasing the thickness of the edge portion of the sintered body , so that thermal stability due to external impacts may be increased, and reliability can be improved by being less affected by moisture, thus, it is possible to increase thermal stability due to external impact, and reliability can be improved by being less affected by moisture. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) fabricating solid electrolyte capacitor; and (b) a solid electrolyte capacitor (C2). DESCRIPTION OF DRAWING(S) - The figure illustrates a cross-sectional view of a sintered body of a solid electrolyte capacitor. Sintered body (110) Conductive polymer layer (130) Carbon layer (140) Silver layer (150)
