The invention relates to a ceramic-plastic composite board and a manufacturing method, the ceramic-plastic composite board comprises a ceramic board and a plastic board, wherein the ceramic board andthe plastic board are processed into the ceramic-plastic composite board through a thermal bonding technology or a composite technology of coating an adhesive. The method comprises the steps that (1)a ceramic plate and a plastic plate are compounded, wherein the edge of the first plastic plate transversely extends outwards, and the edge of the second plastic plate transversely extends and protrudes outwards; (2) the longitudinal distance of a step formed by the first plastic plate from the bottom of the first embedding groove is 8-12 mm and the step distance of the second plastic plate from the lower edge of the ceramic plate to the longitudinal downward direction is 2-3 mm; and (3) the first plastic plate and the second plastic plate are respectively laminated with the ceramic plate by adopting thermal lamination or coating lamination with an adhesive.
