Abstract: A method of manufacturing a pleated product capable of partially pleating a fabric so that boundaries between pleat portions and non-pleat portions can be conspicuous and a fabric for the pleated product used for the method. In this method, a part of the fabric for the pleated product in which one of warp and weft is formed of easy-to-pleat yarn and the other formed of hard-to-pleat yarn is folded along a folding line tilted relative to the warp and the weft, the fabric is pleated up to the folding line in the passing direction of the warp or the weft, and the fabric is unfolded and washed. Effective pleats are formed only in the passing direction of the easy-to-pleat yarn on a plane on one side of the folded portion and not formed in the passing direction of the hard-to-pleat yarn on a plane on the other side of the folded portion.
