1. A cell module comprising a plurality of cells, wherein
each of the plurality of cells has a cylindrical shape and includes a positive-electrode terminal and a negative-electrode terminal disposed on one end of the each of the plurality of cells,
one terminal of the positive-electrode terminal and the negative-electrode terminal is located at a center of the one end, and another terminal of the positive-electrode terminal and the negative-electrode terminal is located on a peripheral edge of the one end and is electrically connected to a side surface of a tube of the each of the plurality of cells,
the each of the plurality of cells includes a connection intervening member on the peripheral edge of the one end,
the connection intervening member includes a tab extending along the side surface of the tube of the each of the plurality of cells and electrically connected to the side surface, and a hole that causes the center of the one end to be exposed,
the plurality of cells make up cell blocks, each of the cell blocks being a block where a plurality of cells adjacent to each other in the plurality of cells are arranged, the one ends of the plurality of cells adjacent to each other being oriented in an identical direction, and the plurality of cells adjacent to each other are aligned in rows,
the cell module further comprises a plate having electrical insulating properties, the plate being on the one ends of the plurality of cells arranged,
the plate includes a hole that causes the one end of each of the plurality of cells to be exposed, and a plurality of conductive members on a surface of the plate, the surface being opposite to a surface of the plate which faces the plurality of cells,
the conductive members extend along the rows of the plurality of cells aligned in each of the cell blocks, and two of the conductive members are disposed for each of the cell blocks, the conductive members each including terminal connectors that pass through the holes to be electrically connected to terminals, having identical polarity, of the plurality of cells included in the cell block, and
an electrical connection between the another terminal and each of the terminal connectors is established through a connection between each of the terminal connectors and the connection intervening member.
