1. A cell stack device comprising:
a cell stack constituted by arraying and electrically connecting cells; and
a pair of conductive members respectively located at two ends of the cell stack in an array direction of the cells and electrically connected to the cells,
each of the pair of conductive members comprising
a power receiving portion facing the cell stack, and
a current extraction portion extending from the power receiving portion,
the current extraction portion comprising an extraction portion body and a connecting portion to be connected to an external device,
wherein when a direction in which the current extraction portion extends from the power receiving unit is defined as a first direction, the current extraction portion has a length in the first direction, and when a direction orthogonal to the first direction is defined as a second direction, the current extraction portion has a width in the second direction, the extraction portion body comprises a first part having a shortest width in the second direction shorter than the width of the current extraction portion and a length in the first direction shorter than an average length of the extraction portion body in the first direction.
