PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor having intensive junction strength between an electrode and a current collector, and excellent charge and discharge characteristics. SOLUTION: In an electric double-layer capacitor having an electrode body, which is formed by integrating a polarizable electrode, containing a carbon material and a bonding material, the bonding material contains one or more kinds of copolymers such as a perfluoro (alkylvinylether/vinylidene fluoride copolymer, a hexafluoropropylene/vinylidene fluoride copolymer, a chlorotrifluoroethylene/vinylidene fluoride copolymer, a tetrafluoroethylene vinylidene fluoride copolymer, a hexafluoroacetone/vinylidene fluoride copolymer and a chlorotrifluoroethylene/vinylene carbonate copolymer. |
