PROBLEM TO BE SOLVED: To provide a anode material for underground buring easy in operability at the time of producing and buring, excellent in mass-producibility and having performance equal to or above that of a conventional product. SOLUTION: This material is composed of an anode of metal, such as magnesim or the alloy thereof and a back-fill molded body covering the anode and molded and soldified into a prescribed shape. In the back-fill molded body in the anode material, breaking strength by a Kiya hardness tester is >=50 kgf/cm2 or density is >=1.5 g/cm3. Therefore, there is no generation of dust at the time of producing or buring, and it is excellent in operability and mass- producibility. |
