Abstract
The present application provides an electric double-layer capacitor capable of reducing an internal resistance without exerting a large stress on a positive electrode body, a negative electrode body, and separators. The electric double-layer capacitor according to the present invention is obtained by housing a capacitor element impregnated with an electrolytic solution in a case. The capacitor element is obtained by stacking and winding a positive electrode body, separators, and a negative electrode body. The positive electrode body has positive electrode current collector tabs fixed on positive electrode current collectors. The negative electrode body has negative electrode current collector tabs fixed on negative electrode current collectors. The paired positive electrode current collector tab are displaced from each other and the paired negative electrode tabs are displaced from each other in a state where the positive electrode body and the negative electrode body are not wound.
