Abstract
In an electrode having a covering layer stacked on a composite layer, an increase in resistance of the electrode is suppressed. An electrode plate includes a composite layer including active material particles and a covering layer including filler particles stacked on the composite layer. In this electrode plate, a particle size (D30) of the active material particle is set to be equal to or smaller than a particle size (D50) of the filler particle.
