PROBLEM TO BE SOLVED: To provide a non-sintered positive electrode for an alkaline storage battery, with which deterioration of battery capacity due to being left standing in an overdischarged state or high temperatures, is suppressed. SOLUTION: The non-sintered positive electrode 3 for the alkaline storage battery contains active material particles 14, having a nickel hydroxide based compound as a principal component and complex oxide particles 15 which have a polyhedron shape, having sharp-pointed corners or angles and have a composition as expressed by general Formula: LiNi<SB>x</SB>Co<SB>y</SB>Mn<SB>z</SB>O<SB>2</SB>(where x, y, and z satisfy the relations 0≤x<1, 0<y≤1, 0≤z<1, and x+y+z=1).
