PROBLEM TO BE SOLVED: To provide the manufacturing method of an electric double-layer capacitor that can realize high capacity density and has stable characteristics. SOLUTION: In the manufacturing method of the electric double-layer capacitor, an electrode body 45 comprising a polarization electrode 42, a separator 44, and a collector 40 that is mainly made of activated carbon in powder or fiber shape as a main constituent is dipped into organic electrolyte 48. In the manufacturing method, apparent volume VAC per 1 g of activated carbon when DC is equal to 2 g/cc is calculated by VAC=VTP+1/DC, where total pore volume per 1 g of activated carbon obtained by nitrogen adsorption, and the true density of carbon are set to VTP and DC. Then, activated carbon is used for the polarization electrode 42, where a characteristic value X calculated by X=VP/VAC while pore volume per 1 g of activated carbon where pore diameter obtained by nitrogen adsorption ranges from 0.8 to 1 nm is set to VP. |
