Abstract: A method for manufacturing an electrochemical device includes the following steps: a step of preparing a positive electrode, the positive electrode including a first current collector and a positive electrode layer containing a conductive polymer; a step of preparing a negative electrode, the negative electrode including a second current collector and a negative electrode layer; and a step of sealing the positive electrode, the negative electrode, and an electrolytic solution in an exterior body. The step of preparing the positive electrode includes a step of holding the positive electrode in depressurized atmosphere and then introducing gas containing CO2 as a primary component into the depressurized atmosphere.

Abstract: A capacitor electrode includes a conductive base member and an electrode part electrically connected to the base member. The electrode part contains carbon particles of a first carbon material capable of adsorbing and desorbing ions. The electrode part further contains voids including first voids with diameters of not less than 0.2 μm and not more than 1.0 μm, and second voids with diameters of not less than 0.05 μm and less than 0.2 μm. The value of (VA×VA)/(VB×M) is greater than 0.022, where VA is the sum of the volumes of the first voids, VB is the sum of the volumes of the second voids, and M is the volume of the electrode part per unit weight of the electrode part.
