A fuel cell is disclosed, which can use space in an apparatus body effectively. The fuel cell comprises a plurality of cells laminated, and a cell box housing the plurality of cells. The plurality of cells include a cell whose size in a first direction orthogonal to a lamination direction is different from that of another cell. The cell box has a shape corresponding to the size of each cell. Furthermore, an electronic apparatus is disclosed, which comprises an apparatus body including a grip portion having a protruding shape; and a fuel cell that is housed in the grip portion and comprises a cell section in which a plurality of cells are laminated in a protrusion direction of the grip portion or a direction orthogonal to the protrusion direction.
