PURPOSE: A manufacturing method of a composite marble board and the composite marble board manufactured thereby are provided to reduce shock and vibration generated when a marble material is processed using a first member welded to the back surface of the marble material. CONSTITUTION: A manufacturing method of a composite marble board is as follows: A first adhesive is spread on both surfaces of a marble material, and first members are attached on both surfaces of the marble material(S110). The first adhesive is cured(S120). A primary composite board composed of the marble thin plate and the first member is formed by cutting the marble material in a horizontal direction(S130). The marble thin plate of the primary composite board is polished(S140). Foreign materials are removed from the primary composite board(S150). A secondary composite board is formed by attaching a second member to the back surface of the first member of the primary composite board using a second adhesive(S160). The second adhesive is cured(S170). A composite marble board is formed by cutting and processing the secondary composite board(S180).
