Abstract: Provided is a lead-acid battery which includes: a power generating element; an electrolyte solution; a container which houses the power generating element and the electrolyte solution; and a lid member which is configured to seal the container and in which an exhaust space and a sleeve member are formed, the exhaust space communicating with an outside, an inside of the container being communicated with the exhaust space through the sleeve member. A bottom surface of the exhaust space is inclined such that a solution in the space returns to the inside of the container. The sleeve member has blocking elements arranged in a spaced-apart manner in an extending direction of the sleeve member. The inside of the container is communicated with the exhaust space through a space formed between the blocking elements.
