The invention provides a base plate and a manufacturing method of the base plate. The base plate comprises a plurality of pieces of fragmented melamine impregnated adhesive film paper, wherein the maximum particle size of the plurality of pieces of fragmented melamine impregnated adhesive film paper is in a range of 2-10 mm; the surface of the fragmented melamine impregnated adhesive film paper isprovided with an adhesive; and the raw material is made into plates through a hot-pressing process, wherein the maximum thickness of the plates is in a range of 3-7 mm. According to the base plate and the manufacturing method of the base plate, residue waste materials obtained in a use process of the melamine impregnated adhesive film paper or torn leftovers which cannot be normally used can be used for manufacturing the base plate, so that waste is avoided. In addition, the manufacturing method is simple in process, new equipment is not needed, production cost is low, the waste is changed into wealth, and economic and social benefits are remarkable.
