PROBLEM TO BE SOLVED: To provide a liquid level indication device for storage battery of which the lowering of an electrolytic solution level injected in a case of a storage battery, and the quantity of water compensating the lowering of the electrolytic solution level, and the specific gravity of the electrolytic solution can be confirmed visually. SOLUTION: As for this liquid level indication device, a funnel-shaped hollow part is formed at a stopper sealing an opening of the storage battery, a transparent window is formed at the upper end of the funnel-shaped hollow part, a plurality of small balls floating in the electrolytic solution are housed in a leg opening downward in a row, the electrolytic solution in the storage battery is filled in and made to flow through the funnel shaped hollow part. The displacement of the liquid level in the storage battery can be confirmed by visually confirming the funnel-shaped hollow part through the transparent window formed at the stopper and observing the state and the number of small balls.
