The present invention provides a manufacturing method of non-woven fabric thin-layer article, which includes the following steps: A. melting polymer raw materials B. drawing the molten polymer materials into textile fibers C. layering the textile fibers in a forming mold to form a thin-layer article, wherein the forming mold is provided with a plurality of concave-convex structures, such that when the thin-layer article is formed in the forming mold, it will also be formed with the flow guiding structure corresponding to the concavo-convex structures. The present invention combines the forming process of the flow guiding structure of the thin-layer article with the forming process of the non-woven fabric in order to shorten the length of the production line and the conveying period of the non-woven fabric.
