PROBLEM TO BE SOLVED: To improve connection reliability between a coupling bolt formed at a capacitor terminal outside a case and coupling hole formed at a collector inside the case. SOLUTION: An anisotropic conductive adhesive 30 of a non-solvent is coated on a coupling bolt 20 before the bolt 20 is screwed into a coupling hole 22. The anisotropic conductive adhesive 30 electrically couples the coupling bolt 20 and the coupling hole 22 by conductive particles 32 at a part under pressure, and the conductive particles 32 shows an electric insulation property covered with an adhesive material at a part not under pressure. Therefore, electrolyte solution filled in the case does not come in direct contact with the conductive particles 32 covered with the adhesive material 34, which enables prevention of corrosion of the conductive particles 32. As a result, reliability of connection of the capacitor terminal and the collector is further improved. COPYRIGHT: (C)2003,JPO
