PURPOSE:To obtain a fine molding excellent in decorative property, by forming decorative ridge forming surface with a longitudinal groove section, applying a curable liquid plastic surface on the decorative ridge forming surface, and curing the liquid plastic surface using ultraviolet rays. CONSTITUTION:A substrate strip 11 is formed with a decorative ridge forming surface 15 having a longitudinal groove section 16, and a curable liquid plastic 21 is cast thereon to form a liquid plastic surface 22. The liquid plastic surface 22 is irradiated with ultraviolet rays to be cured so that the substrate strip 11 may have a plastic decorative ridge 20 integrally.
