A paste-type cadmium electrode for use in an alkaline storage cell, comprising a conductive substrate, an active material layer mainly comprising cadmium oxide and formed on a surface of the conductive substrate, and a conductive layer or a nickel body formed on a surface of the active material layer. The conductive layer either has therein powdered carbon and powdered alkali-resistant metal having a surface area of 0.001 to 0.5 m.sup.2 against 1 g of the active material; comprises powdered carbon, a binder and powdered alkali-resistant metal having an apparent density of 0.2 g/cc or less; or comprises a first conductive layer formed on a surface of the active material layer and comprising powdered alkali-resistant metal and a binder, and a second conductive layer formed on a surface of the first conductive layer and comprising powdered carbon and a binder. The nickel body is dispersed on a surface of the active material layer, the nickel body comprising fiber-type nickel having an average fiber diameter of 1 .mu.m or less and/or powdered nickel having an average grain size of 1 .mu.m or less.
