PROBLEM TO BE SOLVED: To provide a lead-acid battery without generating a spark even if a negative electrode edge cut associated with decrease of an electrolyte occurs. SOLUTION: This lead-acid part is provided with a plurality of negative electrode plates, and a strap composed by integrating lattice body edge parts of the negative electrode plates. The lead-acid battery is characterized by that, for one or more negative electrode plates out of the plurality of negative electrode plates, or the negative electrode plates of a quantity equivalent to not more than 30% of the plurality of negative electrode plates, each thickness of the lattice body edge parts is set larger than those of the other negative electrode plates; a lattice body alloy having excellent corrosion resistance is used as compared with that for the other negative electrode plates; and occurrence of the edge cut of the above lattice body edge parts is delayed as compared with that of the other negative electrode plates by coating the lattice body edge parts with an acid-resistant resin.
