AbstractTo provide a battery having one end of the electrode plate group securely adjoined to the electricity collection plate, and its manufacturing method. One end of the electrode plate group consisting of a plurality of positive electrode plates 18 and a plurality of negative electrode plates 19 with separators interposed between them is stuck to the electricity collection plate 21, 22. The electricity collection plate 21, 22 is provided with a plurality of lead lines 30 at one side in the direction of arranging the electrode plate group 18, 19. The one end of the electrode plate group 18, 19 is pressed against the lead lines 30 of the electricity collection plates 21, 22. A non-contact heat source like an electron beam is applied to the side of the collection plate 21, 22 opposite to the lead lines 30 along them, thus sticking the electrode plate group 18, 19 to the collection plate 21, 22 at high speed without adversely affecting the other parts with heat.
