A combined structure with high conductivity and strength and a manufacturing method thereof are provided to form a sinking pattern on the surface of a bulk material and to coat the sinking pattern with a conductive material in order to show high conductivity and strength. A sinking pattern(12) is formed on the surface of a bulk material(10). An electrically conductive material(30) is coated on the sinking pattern. A photosensitive film is formed on the bulk material. An open site having a predetermined shape is formed on the photosensitive film. The open site is etched to form the sinking pattern. The photosensitive film is removed.
