The folding apparatus comprises: a web supply unit which supplies a web in which plate-type unit cells are arranged at a predetermined interval on a separation film; a winding jig which holds a first unit cell of the web, and which rotates the unit cells such that the unit cells are sequentially stacked and the separation film is interposed between the unit cells; and a Y-axis direction rotating shaft correction unit which corrects the location of a rotating shaft of the winding jig in a vertical direction (Y-axis direction) with respect to a web-proceeding direction, wherein the Y-axis direction rotating shaft correction unit periodically varies the location of the rotating shaft in the vertical direction (Y-axis) with respect to the web-proceeding direction (X-axis) such that the vertical amplitude of the web can be minimized during winding.
