A lead storage battery comprising a battery casing has a first case member (such as a tray) and a second case member (such as a cover) in a superposed relation. The tray has a protruding part for mounting one external terminal, and the cover has a protruding part for mounting the other external terminal. The tray and cover have recessed regions for receiving the protruding parts for mounting the external terminal of an opposing case member of the tray and the cover. The tray has a recessed region for holding a safety valve so that the safety valve is covered by the cover when the tray and the cover are superposed. A small hole is formed in the recessed region such that the small hole is connected with an interior of the battery casing.
