摘要：
According to the present invention, an inexpensive iron sintered substrate used for alkaline storage batteries which has three-dimensionally intercommunicating spaces is improved, and inexpensive alkaline storage batteries using the substrate are provided. The electrode used for the alkaline storage batteries comprises an iron powder sintered substrate having three-dimensionally intercommunicating spaces and plated with nickel and an active material powder filled in the space of the substrate, wherein an oxide film obtained by previously oxidizing iron per se is formed on the surface portions of the substrate which are not plated with nickel.
