PROBLEM TO BE SOLVED: To prevent lubrication problems (for example, occurrence of an undried part, a lubricant film unformed part, accumulation of a lubricant, etc.), by applying the lubricant in good atomized condition in forging of an aluminum alloy. SOLUTION: A lubricant coating nozzle which has an outlet of atomizing compressed air and an outlet of the lubricant arranged in a concentric circle, or a lubricant coating nozzle characterized in arranging the outlet of atomizing compressed air outside the outlet of the lubricant, a lubricant coating device and a forging machine applying the nozzle, and a lubricant coating method and a forging method applying the nozzle can solve the problems.
