An electricity storage device includes an electricity storage module and a cooling device disposed adjacent to the electricity storage module. The cooling device includes a first cooling layer that is adjacent to the electricity storage module and a second cooling layer that is located on the opposite side of the first cooling layer from the electricity storage module. In the first cooling layer, a plurality of first cooling channels that is disposed at intervals in an array direction and first walls that are located between the first cooling channels are formed. In the second cooling layer, a plurality of second cooling channels that is disposed at intervals in the array direction and second walls that are located between the second cooling channels are formed. At least some of the first walls are disposed so as to be offset from the second walls.

A bonding apparatus according to the present disclosure includes a bonding tool that bonds a wire to a terminal, a guide member that guides the wire, a clamp made of a conductive material and capable of fixing the wire, and an electrical property measurement unit electrically connected to the clamp. The clamp is configured to be electrically connected to the wire when the wire is fixed. After the wire is bonded to the terminal using the bonding tool, the bonding apparatus carries out a tensile test for fixing the wire using the clamp and pulling the wire bonded to the terminal with a predetermined load and an electrical property test for measuring an electrical resistance of a junction between the wire and the terminal using the electrical property measurement unit.
