PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor using a polarizing electrode which will not block the polymerization reaction of a polymer electrolyte, in an electric double-layer capacitor with high safety which uses the polymer electrolyte. SOLUTION: In an electric double-layer capacitor, polarizing electrodes containing an active carbon species are disposed opposite to each other via a polymer electrolyte. The electric double-layer capacitor includes a polymer obtained by reacting a piperazine derivative, in which the pH of the active carbon species is in the range of 4 to 9, and the polymer electrolyte is represented by Formula (A) (refer to Chemical Formula 1), a hydrosilylated compound represented by Formula (B) (refer to Chemical Formula 2, and a compound represented by Formula (D).
