Abstract: A positive electrode material for an alkaline storage battery includes: nickel hydroxide; and at least one of a Sr compound, a Ca compound, and a compound of at least one element selected from the group consisting of Y and lanthanide elements of atomic number 62 (Sm) to 71 (Lu). An A element as at least one element selected from the group consisting of Al, Ga, Mn, and Mo is held in solid solution in a crystallite of the nickel hydroxide. The content of the A element, [A]/([Ni]+[A]), is 5% or more and 16% or less (where [A] represents the molarity of the A element in the crystallite and [Ni] represents the molarity of Ni). The nickel hydroxide includes α-phase nickel hydroxide and β-phase nickel hydroxide.

Abstract: A layered electrode group according to the present invention includes a positive electrode plate, a negative electrode plate, and a separator. The positive electrode plate is formed into a substantial U-shape by disposing two active material retaining portions retaining the positive active material opposite to each other. The negative electrode plate is formed into a substantial U-shape by disposing two active material retaining portions retaining the negative active material opposite to each other. The positive electrode plate and the negative electrode plate are layered such that at least one active material retaining portion at the positive electrode plate is sandwiched between two active material retaining portions at the negative electrode plate.
