Abstract
In an activated cathode and a method for manufacturing the activated cathode, a first layer which contains nickel or cobalt as a main component is formed on a metal substrate, and a second layer which contains platinum or ruthenium as a main component is formed on the first layer. It is preferable that the first layer is formed of Raney nickel and the second layer has a large cathode working area, or it is also preferable that the first layer is formed of nickel oxide or cobalt oxide, and the second layer is formed of fine platinum or ruthenium particles and has a large cathode working area.
