PROBLEM TO BE SOLVED: To perform the injection-formation with the high precision by using a metallic material as the forming material. SOLUTION: In the injection apparatus for injecting light metal material into a forming metallic mold 6, a hopper part 14 for charging the forming material 4, is provided. Further, a heater 15 for heating the forming material 4, and cylinder part 11 having a screw 12 for kneading, melting and also, injecting the forming material 4, are included. Furthermore, a nozzle part 13 for injecting the forming material 4 kneaded and melted in the cylinder 11 into the forming metallic mold 6, is arranged. Then, a flowing path surface for forming material 4 is formed by coating a film 20 with a coating material having >=200 deg.C the melting point: at 1 atmospheric pressure on the inner surface of at least a nozzle head 18 in the nozzle part 13.
