Abstract
A safety valve is disposed to cover at least a portion of the center line of the lid plate between the pair of terminals for the positive electrode and the negative electrode. The distance from the center line of the lid plate to end portions of the components to be energized on the safety valve side is equal to or less than the distance from the center line of the lid plate to the outermost circumference of the safety valve. The shadow area obtained by projecting an opening portion of the safety valve in operation onto the plane of the lid plate does not overlap with the respective shadow areas obtained by projecting the electrically connected components, such as the external output terminals for the positive electrode and the negative electrode, onto the plane of the lid plate.
