A method of manufacturing an environmental protective paper doll includes the steps of using recycle paper as the manufacturing material; adding appropriate proportion of water to the paper pulp after a slight filtering to make a paste; pressing the vacuum mold on the protruded mold plate after tying the net; submerging in a trough containing the pasty paper pulp; drawing out the liquid in the vacuum shaping mold to facilitate the formation of an embryo layer with appropriate thickness on the tying net of the protrusion member; engaging the upper mold and the lower mold together and preliminarily removing the water content; baking the semi-finished embryo layer for dehydration; pasting the front and rear halves with glue; trimming the rough edge and coating the paper surface with a layer of golden paint to increase the hardness of the surface; and then painting with the stylish colors and forming the paper doll.
