PURPOSE: A method for manufacturing a control knob for a vehicle is provided to maximize discrimination by filling characters or patterns with synthetic resins of transmissive materials. CONSTITUTION: The surface of a panel for a housing is etched (S110). The etched panel for the housing is foamed (S120). The panel for the housing is integrated with transmissive resins. The surface of the panel for the housing is postprocessed (S140). An engraved message is formed on the surface of the panel for the housing (S150).
