PROBLEM TO BE SOLVED: To provide an electrode for a secondary battery capable of exhibiting excellent performance at high speed charge / discharge. In an electrode for a secondary battery 101 having a porous metal current collector 102, the surface of the porous metal current collector facing the counter electrode is composed of a porous metal oxide 104, and the porous metal current collector 102 is porous. The current collector has an electrode active material thin film layer 103 formed on the surface of the inner hole, and the porous metal current collector is at least one selected from aluminum, tantalum, niobium, silicon, and an alloy containing one or more of these. It consists of seeds. [Selection] Figure 1 |
