<p>PROBLEM TO BE SOLVED: To provide a battery module and battery pack excellent in cell cooling performance.SOLUTION: By providing projecting parts 22, the heat conductive plate 21 of a battery module 10 is able to reduce the contact area between the heat conductive plate 21 and a heat conductive sheet 31, compared to a configuration in which the entire area of the underside of the heat conductive plate 21 is brought into contact with it. A central part in a longitudinal direction Y is larger in the total of the contact areas between each projecting part 22 and a heat exchanger 30 than both end parts in the longitudinal direction Y. Thus, the central part where heat easily accumulates is larger in the contact area between each projecting part 22 and heat exchanger 30, making cooling performance better than both the end parts.</p> |
