A manufacturing method of a sports skateboard includes the steps: selecting the materials of a board core; machining a groove; manufacturing a PU lateral strip; manufacturing the board core: curing the board core with the PU lateral strip in the groove, and placing on a machining part again to manufacture the board core required by design through computer program control; molding the skateboard: wrapping the board core with glass fiber or carbon fiber materials, brushing resin on the board core wrapped with the glass fiber or carbon fiber materials, placing the board core with the resin between a bottom board and a surface board and jointly placing into a mold, performing compression molding in the mold with pressure being 6-8MPa and temperature being 80-90 DEG C, and stripping the mold to obtain the sports skateboard. The manufacturing method of the sports skateboard has the advantages that the method is simple in process, high in automation level, high in efficiency, high in machining precision, high in procedure flexibility, wide in application range, simple in temperature and pressure requirements, low in energy consumption, few in requirements and low in cost, many kinds of materials can be selected, and the sports skateboard can be used normally in a wet and slippery environment due to the fact that an antiskid pad is adhered to the sports skateboard.
