An electrical storage apparatus of the invention has a first and a second electrical storage module arranged in a first direction. Each of the electrical storage modules has a plurality of cylindrical electrical storage elements, a support plate and a casing. The support plate supports a portion of each of the electrical storage elements. The casing surrounds the plurality of electrical storage elements and the support plate to form a space in which air moves. The casing has an air intake opening for moving air from a passage into the space and an air discharge opening for moving the air in the space out of the casing. The passage for moving the air in a second direction orthogonal to the first direction is formed between the first and second storage modules, and the air is used for regulating temperature of each of the electrical storage modules.
