Abstract: The present invention provides an electrode that is excellent in conductivity and improves the power density and energy density of a power storage device, a method for manufacturing the same, and a power storage device using the same. The electrode of the present invention is an electrode containing at least a graphene aggregate having a particle diameter of 0.1 μm or more and less than 100 μm, wherein the graphene aggregate is an aggregate of graphene basic structures each having graphene layers among which a fibrous material is located. A method for manufacturing the electrode of the present invention comprises a step of mixing the above-mentioned graphene basic structures with at least a lower alcohol having 1 or more and 5 or less carbon atoms to form a graphene aggregate in which the graphene basic structures are aggregated, and a step of forming a film using the graphene aggregate.
