An intravascular stent () comprises a framework with openings and at least one radiopaque structure (). Each radiopaque structure () comprises fixed bodies and radiopaque markers () filled in the fixed bodies. The fixed bodies are connected with the framework, and are at least partially disposed in the openings. The envelope enclosed area of all the radiopaque markers () in each radiopaque structure () is less than or equal to 2 mm, and a sum of effective areas of all the radiopaque markers () in each radiopaque structure () is greater than or equal to 0.15 mm, and a ratio of said sum of effective areas to said envelope enclosed area is greater than or equal to 1:5. The radiopaque structure () has a desirable visibility, and does not substantially affect the crimped diameter of the intravascular stent ().
