Abstract

There is provided a cooling structure between battery cells which allows a temperature rise of adjacent battery cells to be restrained more efficiently even for an appearance of an abnormally heat-generating battery cell. A cooling structure between battery cells disposed side by side so that two side surfaces face each other, the cooling structure between the battery cells includes, formed of plate-shaped metal members each having a thermal conductivity of 100 W/m·K or more and a thickness of 0.3 mm or more, and being in contact with the respective facing side surfaces of the adjacent battery cells, and a heat insulating layer disposed between the plate-shaped metal members, and having a thermal conductivity of 1.0 W/m·K or less and a thickness of 0.5 mm or more, a multi-layer structure of cell/metal member/heat insulating layer/metal member/cell, and the cooling structure further includes a cooling member present in the vicinity of the plurality of battery cells, wherein one end portion of each of the plate-shaped metal members is in contact with the cooling member.
