PROBLEM TO BE SOLVED: To provide a method of manufacturing the positive electrode grid body for lead-acid storage battery capable of preventing short circuit of the positive electrode grid body for lead-acid storage battery due to elongation deformation caused by corrosion thereof, while suppressing reduction in mechanical strength and influence on the electrical characteristics, and to provide a lead-acid storage battery.SOLUTION: A method of manufacturing the positive electrode grid body 1 for a lead-acid storage battery in which a grid body having a frame bone 2, and a vertical bone 3 and a lateral bone 4 arranged like a grid in the frame bone are formed from a plate of lead or a lead alloy produced by any one of gravity casting, pressure casting, continuous casting or rolling, includes a step for subjecting a predetermined point of the frame bone 2 to high deformation thus forming a low corrosion resistance point. |
