An absorbable iron-based alloy implantable medical device, comprising an iron-based alloy substract and a complex body, wherein the complex body comprises a complexing agent. In a physiological solution, the iron-based alloy substract can react with the complexing agent to generate a water-soluble iron complex having solubility in the physiological solution of no less than 10 mg/L. A corrosion product generated after the absorbable iron-based alloy implantable medical device is implanted in a human body can be quickly metabolized/absorbed by the body.
