Claim 5:
6. The additive manufacturing device according to claim 3, further comprising:
flow rate changing means for causing the flow rates of the inert gases ejected from the first nozzle, the second nozzle, and the window portion nozzle to be different from each other,
wherein the flow rate changing means includes a configuration in which a height of the flow path of the first nozzle, a height of the flow path of the second nozzle, and a height of the flow path of the window portion nozzle are different from each other, and a resistance imparting portion that imparts resistance to the inert gas flowing through at least one flow path among the flow path of the first nozzle, the flow path of the second nozzle, and the flow path of the window portion nozzle.
