<p>PROBLEM TO BE SOLVED: To provide a cooling structure of a battery cell which inhibits variations in battery cell temperatures and prevents increases in the weight and the cost.SOLUTION: A cooling structure of a battery cell includes: a battery exterior material 21 which encloses a power generation element; and a sealing part 22 which is formed by heat sealing a periphery of the battery exterior material 21, seals the power generation element in the battery exterior material 21, and has a heat radiation part 22a which extends in a flow direction of air flowing at the outer side of the battery exterior material 21. A contact area between the heat radiation part 22a at the downstream side of the air flow and the air is formed so as to be larger than a contact area between the heat radiation part 22a at the upstream side and the air.</p> |
