A cell module comprises: a cell stack comprising multiple cells which are electrically connected to each other; a plate-shaped heat dissipating member arranged such that it extends along a direction in which the multiple cells are arranged, and such that it is thermally connected to the multiple cells ; and an intervening layer arranged between the cell stack and the heat dissipating member, and configured to allow heat to propagate from the cell stack to the heat dissipating member, and to suppress a relative displacement between the cell stack and the heat dissipating member.
