CONSTITUTION: A manufacturing method of mixed plywood includes a step for laminating a plurality of low-grade panels(20,21,22,23) which are manufactured with lauan, Oregon pine, poplar, and tamaracks and a step for attaching the laminated low-grade panels on the top and the bottom of high-grade panels(100) which are made with oak, walnut, maple, elm, and mahogany wood. An adhesive is casein, viscose, or glutamine. The adhesive is pressed and attached on the panels with pressure of 10 kg/cm^2 - 18 kg/cm^2 at a temperature of 100 ~ 150 degrees.
