To provide a weaving method for a warp multiple cloth effective for preventing the generation of defective woven texture even by generating a tension difference between the warps of individual layers.

The warp multiple cloth having different warp density by layers is woven by using a modified pitch reed having reed dents to set the reed mark width to be proportional to the warp density of each layer or a modified pitch reed having reed dents to form the reed mark width larger than the product of the number of warps crossing in the cross-time of the loom and the diameter of the warp, and the warp of each layer is inserted into different reed spacings. The warp multiple cloth having different warp density between the layers is produced by the method.
