PROBLEM TO BE SOLVED: To provide a simple gas sampling device and a gas sampling method for enhancing analytical accuracy, in gas sampling for collecting an analytical sample of treating gas in an iron mill by using an injector. SOLUTION: This gas sampling device collects the analytical sample of the treating gas in the iron mill by using the injector. The gas sampling device and the gas sampling method are characterized by substituting the gas inside the injector with the analytical sample by arranging a three-way valve in a conducting pipe on the injector inlet side.
