PROBLEM TO BE SOLVED: To provide a method for condensing zinc with which can recover as the metallic zinc, conventionally vaporized zinc recovered as zinc oxide. SOLUTION: When the vaporized zinc is condensed into liquid zinc in oxidizing gas-containing atmosphere, the vaporized zinc is cooled with a larger cooling rate than an oxidizing ratio of the zinc by using a heating furnace 4, etc. As raising the cooling speed, the condense of the vaporized zinc is promoted, and the vaporized zinc is not changed into the zinc oxide, but this vaporized zinc can be condensed as the metallic zinc.
