PROBLEM TO BE SOLVED: To reduce reaction force of a heat transfer sheet held between a power storage module and a cooling plate. ! SOLUTION: In a first step, a heat transfer sheet 21 which comprises a pressure receiving surface 21a that contacts a cooling plate 12 or a power storage plate 13 and a free surface 21b which is perpendicular to the pressure receiving surface 21a and surrounds the periphery of the pressure receiving surface 21a is manufactured. In a second step, the required reaction force of the heat transfer sheet 21 is decided. In a third step, the reaction force produced by the heat transfer sheet 21 is reduced lower than the required reaction force by reducing the ratio (shape factor S) of the area A of the pressure receiving surface 21a to the area F of the free surface 21b by cutting the heat transfer sheet 21 into a plurality of pieces. Therefore, damage to the power storage module 13 and its fixing section due to the reaction force from the heat transfer sheet 21 can be prevented. ! COP |
