An alkaline storage battery including a bottomed cell casing assembled as either one of positive and negative terminals, a closure cap assembly coupled with an opening of the cell casing in a liquid-tight manner as the other terminal to hermetically seal the interior of the cell casing and a generator element composed of positive and negative electrodes assembled within the cell casing, wherein a current collecting plate extended from either one of the positive and negative electrodes is welded at least at two spaced portions thereof with a bottom surface of the closure cap assembly to enhance mechanical strength and the vibration resistance property of the storage battery and to reduce internal resistance of the storage battery.

[ What is claimed is:] [1.] An alkaline storage battery including a bottomed cell casing comprising either one of positive and negative terminals, a closure cap assembly comprising the other one of said positive and negative terminals and which is coupled with an opening end of said cell casing in a liquid-tight manner to hermetically seal the interior of said cell casing, and a generator element comprising positive and negative electrodes assembled within said cell casing,wherein a current collecting plate extended from either one of said positive and negative electrodes has a distal end portion welded to a bottom surface of said closure cap assembly before said closure cap assembly is coupled with the opening end of said cell casing and an intermediate portion which engages the bottom surface of said closure cap assembly at a position spaced from the distal end when said closure cap assembly is coupled with the opening end of said cell casing to seal said generator element contained in said cell casing, whereby, upon the flowing of an electric current between said cell casing and said closure cap assembly, said intermediate portion is welded to the bottom surface of said closure cap assembly.
