PROBLEM TO BE SOLVED: To improve current collecting property of a grid base for a lead-acid storage battery. SOLUTION: On the grid base for the lead-acid storage battery formed into a square shape surrounded by surrounding skeleton, having an ear part protruded from the surrounding skeleton, having lateral and vertical intermediate skeletons perpendicularly crossing each other formed between surrounding skeletons facing each other; supplemental intermediate skeletons extending inward from the surrounding skeleton on which the ear part is protruded, not reaching the surrounding skeleton of opposite side, are formed between the intermediate skeletons. The intermediate skeletons positioned near to the protruded ear part and the supplemental intermediate skeletons are formed so as to become thicker as it is headed to the surrounding skeleton having the ear part, and the surrounding skeleton having the ear part is formed so as to become thicker as it is headed to the ear part.
