Title:
SOLID-STATE ELECTROLYTIC CAPACITOR
Document Type and Number:
Japanese Patent JP3806503
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain generation of gas under high temperature environment, by coating an outer circumference of a capacitor element wherein a conductive polymer layer is formed with a thermosetting resin layer or a graphite later, and sealing an opening part of a case by a rubber sealing member.
SOLUTION: In a solid-state electrolytic capacitor, a conductive polymer layer such as oxidation polymerization of 3,4-ethylene dioxy thiophene is formed inside a capacitor element 1 whereon an anode foil and a cathode foil opposite to the anode foil wherein a formation film is formed are wound interpoing a separator paper. Then, the capacitor element 1 is put in a case 4 and an opening part is sealed by a sealing member 3 such as butyl rubber. An outer circumference of the capacitor element 1 is coated with a thermosetting resin layer 21 or a graphite layer 22. The sealing member 3 is provided with a through-hole 30 and a lead 13 of the capacitor element 1 is led out and a lead tab terminal 12 is fit in the through-hole 30. Cross drawing processing and curling processing are carried out in an area near an opening part of the case 4 whereon the sealing member 3 is mounted.
