The invention provides a battery positive plate capable of improving battery output characteristics, an alkaline storage battery, and a method for manufacturing the battery positive plate. The positive plate (15) is formed in a manner that a substrate (25) composed of a three-dimensional porous body is filled with a filling (26) including active materials. The positive plate (15) is divided into five equal sections in the thickness direction. The skeletal density of the three-dimensional porous body in the center layer is higher than 1.5 times and lower than 3 times of the skeletal density of the three-dimensional porous body in at least one of the two most superficial structures arranged on the outermost side.
