<p>PROBLEM TO BE SOLVED: To prevent the shape of a passage in which a refrigerant flows from changing due to deformation of a power storage element such as an electric cell thereby inhibiting the aging deterioration of a coolant pipe forming the refrigerant passage and maintaining the cooling capability over a long period.SOLUTION: A power storage module 10 includes a battery pack 100 where multiple electric cells 101 are electrically connected. The power storage module 10 includes: a metal cooling pipe 180 forming a passage in which a refrigerant flows; and a heat transfer plate 170 having recessed parts 172 which hold the cooling pipe 180 and protruding parts 173 thermally connected with the electric cells 101. Each cooling pipe 180 has a pipe heat transfer part that is thermally connected with the electric cells 101 without disposing the heat transfer plate 170 therebetween.</p> |
