    • PROBLEM TO BE SOLVED: To provide a sintered substrate for an alkaline storage battery having sufficient strength compared with a conventional sintered substrate even if its porosity is made higher. SOLUTION: The sintered substrate has a constitution that a pore radius in which an occupying volume ratio with respect to the whole pore volume has a peak is 5-7 μm, and an occupying volume ratio of a pore radius which has a larger pore radius than 8.5 μm becomes 11% or lower. Since such a sintered substrate has smaller macroaggregated pores compared with the conventional sintered substrate and the hole diameter distribution of the pore is more homogeneous, this has sufficient strength even if the porosity is elevated. Moreover, since a cadmium negative electrode using such a sintered substrate is superior in gas absorption performance, this has an effect of being able to reduce the pressure of a battery interior when in charge.
