A cylindrical type alkaline storage battery includes a cylindrical container having electrical conductivity, and an electrode assembly contained in the container, the electrode assembly being a roll obtained by rolling up a positive electrode plate, a negative electrode plate and a separator together. Provided that the maximum diameter of the container is Dmax and that the number of turns of the positive electrode plate is N, the relationship N>=[0.5xDmax-2.65] is fulfilled (where "[]" represents Gauss' notation). Where the battery is of AA size, for example, the number N of turns is four or more. Also, provided the circumferential position of the roll starting end of the positive electrode plate is a reference position, the angle theta measured from the circumferential position of the roll terminating end of the positive electrode plate to the reference position ranges from 180° to 270°.
