A power storage pack includes a plurality of power storage modules each having a plurality of power storage devices arranged in first direction X and binding members that bind the plurality of power storage devices, and heat transfer members that transfer heat between the plurality of power storage modules. The plurality of power storage modules includes at least a first power storage module and a second power storage module. Each heat transfer member has first connecting parts thermally connected to a surface of the first power storage module, the surface being parallel with first direction X, second connecting parts thermally connected to a surface of the second power storage module, the surface being parallel with first direction X, and coupling parts thermally coupling the first connecting parts to the second connecting parts. The first connecting parts and the second connecting parts are arranged in such a way as to be shifted from each other in first direction X.
