To provide a battery pack cooling structure capable of leading a cooling fluid to each part within a casing by effectively utilizing an installation member for installing a battery pack in a vehicle body so as to attain simplification or compaction of the battery pack.SOLUTION: The present invention relates to a battery pack cooling structure 21 comprising: a casing 13; a battery pack 11 including an installation member 17 extending from one side of the casing to the other side; and a fluid lead-in system 25 for leading a cooling fluid to each part within the casing. One end side of the installation member is constituted of an opening-side cylindrical member and the other side is constituted of a bottom-side cylindrical member. An intermediate cylindrical portion 17c is settled within the casing, and both the ends are installed in a vehicle body at one end side and another end side of the casing. A lead-in part 27 is included in the opening-side end of the installation member, and a lead-out part 29 for leading out the cooling fluid to the inside of the casing is included in the intermediate cylindrical portion. The installation member is defined as a channel 31 for leading the cooling fluid into the casing.SELECTED DRAWING: Figure 2
