SOLID-STATE ELECTROLYTIC CAPACITOR

摘要

PURPOSE:To reduce trouble of an electrical short circuit by a method wherein a conductor which is composed of the following and which satisfies specific condition is used as a cathode layer or an adhesive: a mixed power of a palladium powder and a coating conductive powder in which a graphite powder has been coated with a palladium metal; and an organic high polymer. CONSTITUTION:A conductor is composed of the following: a mixed powder of a palladium flakelike powder with particle diameters of 1 to 30mum and a coating conductive powder in which the surface of a graphite flakelike powder with particle diameters of 1 to 50mum has been coated with a palladium metal in a thickness of 0.1 to 2mum; and an organic high polymer. In addition, a conductor in which a weight ratio of the palladium flakelike powder to the coating conductive powder of the mixed powder is (9.5 to 2.5):(0.5 to 7.5) and a weight ratio of the mixed powder to the organic high polymer is (9.5 to 5.0):(0.5 to 5.0) is used as a cathode layer 12 or as an adhesive 13 between the cathode layer 12 and a cathode terminal 10. Thereby, trouble of an electrical short circuit is reduced; and change in a leakage current can be reduced.
