PROBLEM TO BE SOLVED: To provide a manufacturing method of a lead storage battery with excellent workability in welding and variation of thickness of a strap 6. SOLUTION: A lead component 1 having lug insert portions 2 and protrusion portions 11 projecting outwardly at its center in the direction of thickness is cast in a book mold method. A plurality of positive electrode plates and negative electrode plates are layered via separators, and a lug potions 9 of each of the electrode plates are put between comb teeth 12 to dispose an electrode pole component 19 on the comb teeth 12. The lug portion 9 and the ear insertion portion 2 of the lead component 1 are engaged to each other. In this state, the lug portion, the lead component 1 and the electrode pole component 18 are melted by heating them from the above using a burner 3, and they are solidified to form the electrode pole 8 and a strap 6.
