Abstract
A spacer is used with a unit cell that has a cell body including a power-generating element and formed to have a flat shape and an electrode tab extending out from the cell body. The first spacer has a protrusion, a recess, and an opening. The protrusion has a protruding shape and is inserted into a hole or notch provided on the electrode tab to guide the electrode tab. The first recess has a recessed shape, and is separated from the electrode tab around the base of the protrusion. The first opening allows a portion of the first recess to communicate with a side surface of the spacer.
