Abstract
A redox flow battery electrode includes an aggregate of a base containing carbon. When, on a cross section of the base, a circle that is centered at a center of gravity of the base and that has a diameter which is 95% of an isoarea equivalent circle diameter of the base is defined as a reference circle, the base includes a plurality of penetrating holes which extend from a surface toward an interior of the base and whose paths along extension directions of the penetrating holes are partially present within the reference circle.
