A module battery is housed in a module battery housing rack. In the module battery, an electric cell is housed in a container. The electric cell is for a sodium-sulfur battery. The container is provided with a high thermal conductive wall having a relatively high thermal conductivity and a low thermal conductive wall having a relatively low thermal conductivity. A first portion of a plate overlaps the outer surface of the high thermal conductive wall and a second portion of the plate protrudes from the outer surface of the high thermal conductive wall. The second portion surrounds the first portion. A first main surface of the plate is brought into direct contact with the outer surface of the high thermal conductive wall at the first portion and it is apart from the container at the second portion. A second main surface of the plate is exposed to a space, to which heat is allowed to radiate. An opening may or may not be formed at the first portion. A thermal conducting medium may be held between the first wall and the first portion. |
