Claim:
1. A composite material comprising at least one magnesium component made of magnesium or a magnesium alloy, and at least one organic anti-infective agent, whereby the solubility of the anti-infective agent in water at room temperature is less than 10 grams per liter, in the form of a geometrical body made up of the magnesium component, and the surface of a magnesium body made of the magnesium component is partly or fully covered by the anti-infective agent, the thickness of anti-infective coating being 0.001 to 1 mm, wherein the magnesium component consists of pure magnesium having a total impurities content of less than 0.05% by weight or a magnesium-calcium alloy having a calcium content of 0.1 to 1.0% by weight, and the total amount of rare earth metal in the magnesium component is less than 50 ppm, wherein the anti-infective agent is present in a concentration of 0.1 to 100 mg per gram of absorbable implant material, and wherein the magnesium component of the composite material is a wire and has a diameter of less than 500 μm, or both components of the composite material comprise a two-dimensional geometry which are layered into a parallel composite and an individual layer of the magnesium component in the composite material has a thickness of less than 500 μm.
