An electric storage apparatus comprising:
- a plurality of electric storage devices arranged side by side, each electric storage device comprising:
- a case comprising a plurality of walls including:
- a terminal wall, an electrode terminal being formed on the terminal wall, the terminal wall including a long side and a short side;
- a bottom wall opposite to the terminal wall, the bottom wall including a long side and a short side;
- a short sidewall connecting the short sides of the terminal wall and the bottom wall;
- and
- a long sidewall connecting the long sides of the terminal wall and the bottom wall, the long sidewall comprising a greatest area of the areas of the plurality of walls;
- and
- an electric storage element which is housed in the case and separated from an inner surface of the short sidewall, the electric storage element being in electrical connection with the electrode terminal;
- and
- a sheet-shaped heat transfer member which is in contact with an outer surface of the short sidewalls of the plurality of electric storage devices, the sheet-shaped heat transfer member contacting substantially an entirety of the outer surface of the short sidewalls,
- wherein a distance, in a direction parallel to the terminal wall and the short sidewall and intersecting the long sidewall, between an inner surface of the long sidewall and the electric storage element, is less than a distance between an inner surface of the bottom wall and the electric storage element.
