SOLUTION: The nitrogen manufacturing method uses a main heat exchanger for cooling material air, a rectifying tower for separating and refining nitrogen from the air, and the expansion turbine for giving adiabatic expansion to exhaust gas from the rectifying tower to generate cold. Herein, the nitrogen gas from the rectifying tower and the exhaust gas pass through the main heat exchanger to cool the material air. Part of the exhaust gas extracted form the rectifying tower passes as a cold source through the expansion turbine, while the nitrogen gas is introduced from the rectifying tower to the pressure rise side of the expansion turbine where pressure is applied to the nitrogen gas.
