Abstract
An electrode includes an expanded grid and an active material provided on the grid, the thickness of the grid is the same as the strand and connecting sections of the strand, presenting a waveform as a whole. When this grid is used in the electrode as a current collector, the connecting sections are located near the center of the thickness direction of the electrode and strand are arranged by projecting upward and downward, respectively, from the boundary where the connecting sections are situated. Accordingly, a lead-acid storage battery having long life characteristics is made available.
