<p>The present invention provides a cell unit that can be connected in series or parallel without using a bus bar and without welding or bonding using a fixing tool such as a bolt. The characteristic of the present invention is, e.g., as follows. A cell unit in which a plurality of single cells provided with a cell can housing a positive electrode, a negative electrode, and a separator, and a positive electrode terminal and a negative electrode terminal protruding from the cell can, are stacked and electrically connected to each other; the positive electrode terminal and the negative electrode terminal of single cells that are arranged adjacent to each other being in contact with each other at a surface perpendicular to the direction in which the single cells are stacked, forming a terminal contact part; an insulation block being provided between a plurality of terminal connection parts formed by stacking a plurality of the single cells; and the insulation block being in contact with the terminal connection parts. The present invention can thereby provide an inexpensive and lightweight cell unit.</p> |
