1. A power storage pack comprising:
a plurality of power storage modules, the power storage modules each including a plurality of power storage devices arranged in a first direction and a binding member that binds the plurality of power storage devices; and
a heat transfer member that transfers heat between the plurality of power storage modules,
wherein the plurality of power storage modules includes at least a first power storage module and a second power storage module,
the heat transfer member includes:
a first connecting part thermally connected to a surface of the first power storage module, the surface being parallel with the first direction;
a second connecting part thermally connected to a surface of the second power storage module, the surface being parallel with the first direction; and
a coupling part thermally connecting the first connecting part to the second connecting part, and
the first connecting part and the second connecting part are arranged while being shifted from each other in the first direction, and
wherein the heat transfer member includes a plurality of a first connecting parts each being the first connection part and a plurality of a second connecting parts each being the second connection part,
the plurality of first connecting parts and the plurality of second connecting parts are lined up alternately in the first direction,
the first power storage module and the second power storage module include second surfaces, respectively, the second surfaces directing a same direction,
the heat transfer member is disposed to overlap two of the second surfaces,
the coupling part extends in the first direction between the first power storage module and the second power storage module in a view in a direction in which the heat transfer member and the second surfaces overlap each other,
the plurality of first connecting parts project from the coupling part toward the first power storage module and are connected to the second surface of the first power storage module, and
the plurality of second connecting parts project from the coupling part toward the second power storage module and are connected to the second surface of the second power storage module.
