Abstract:
An upper rotating body is rotatably installed on a lower traveling body. An electricity storage module is mounted on the upper rotating body. The electricity storage module includes electricity storage cells each having at least a pair of electrodes led out from edges of a plate-like portion. The electricity storage cells are stacked in the direction of the thickness of the plate-like portions, and the electrodes of electricity storage cells adjacent to each other in the stack direction are made to be in contact with each other to connect the electricity storage cells in series. At least some of the electrode pairs, which are each composed of a pair of electrodes in contact with each other, each have a bridge structure having the electrodes bent in the direction in which the electrodes approach each other and also having the outer surface of one electrode and the inner surface of the other electrode in contact with each other.
