A metal hydride electrode, in which a metallic cobalt powder is mixed within a mixing range of 3 to 20 weight percent, with a hydrogen absorbing alloy powder formed by substituting a part of the Ni of the alloy expressed by a rational formula of MmNi5 with Al and at least one kind of Fe, Cu, Co, Mn, and the mixed powder is loaded into a porous alkaline-proof metal body. A nickel electrode, in which a cobalt monoxide powder is mixed with an active material powder within a mixing range of 5 to 15 weight percent, the active material powder comprising zinc within a range of 2 to 8 weight percent, under a solid solution state in a crystal of nickel hydroxide powder assuming a spherical shape including an inner pore volume of 0.14 ml/g or less, and the mixed powder is loaded into a porous alkaline-proof metal body. A nickel-hydrogen battery consists of the foregoing metal hydride electrode and the foregoing nickel electrode wound together with a separator between them and immersed in an aqueous solution of potassium hydroxide and sealed, after which they are maintained under standing conditions for 5 hours or more.
