The utility model relates to a novel capillary ending embolism agent, which comprises a metallic core and a binding agent. The utility model is characterized in that the metallic core is connected by the binding agent to form a granular structure. The utility model has obvious advantages of good visibility under an X-ray, moderate specific gravity, convenient sedimentation in the capillary, and low price; the phenomenon of back flow is not easy to occur, erroneous embolism can be effectively avoided, and checking of nuclear magnetic resonance (MRI) can be carried out after the embolism is finished. The utility model is the material of the novel capillary ending embolism agent.
