Claim Text:
1. A method of manufacturing an electric storage apparatus comprising the steps of: forming an active material layer in a predetermined width on a partial region of a collector plate to manufacture a positive electrode plate and a negative electrode plate; placing a separator between the positive electrode plate and the negative electrode plate; and impregnating the active material layer in each of the positive electrode plate and the negative electrode plate and the separator with an electrolytic solution, wherein, in manufacturing at least one of the positive electrode plate and the negative electrode plate, a waveform is formed on an edge of the active material layer in a width direction, and a set value Wn of the width of the active material layer and a variation ΔW of the width of the active material layer are set to satisfy a condition of the following expression (II),
