The invention relates to a method for manufacturing embossed release paper and its structure. The unwinding machine rolls out the entire roll of sheet-shaped substrate to a rubber-coating wheel, and cooperates with the pressing wheel to evenly coat the surface of the sheet-shaped substrate with a release agent. The excess release agent is then scraped off by a wire bar, and the sheet substrate coated with the release agent is sent to the drying device for colloid drying, and then the sheet substrate is sent to the embossing device for texture heat embossing To form the embossed release paper, and finally the embossed release paper is cooled by the cooling wheel and sent to the coiler to be wound into bundles.
