Beschreibung
Zusammenfassung:	A secondary battery electrode includes an active material layer configured to be provided on a current collector and be obtained by stacking a plurality of active material sub-layers composed of an active material. Pores of which pore diameter along a thickness direction of the active material layer is 3 to 300 nm are formed along a boundary between the active material sub-layers, and at least a part of the pores is filled with an electrolyte and/or a product arising from reduction of the electrolyte upon assembling of a secondary battery.
