PROBLEM TO BE SOLVED: To surely carry out both the suppression of the swelling of a positive electrode mixture and smoothing electrolytic solution absorption into the positive electrode mixture 21 in a cylindrical battery, and by this, to improve productivity by preventing an inner short circuit and by obtaining the superior stability of discharge, and by shortening a process time from the injection of the electrolytic solution to sealing. SOLUTION: The upper end face of the cylindrical positive electrode mixture 21 loaded into a bottomed cylindrical positive electrode can 11 is pressed down by a circular seat plate 51, its circular seat plate 51 covers the whole upper end face of the positive electrode mixture 21, and a gap d to make the electrolytic solution easily permeable is formed between the upper end face of the positive electrode mixture 21 and the circular seat plate 51.
