PROBLEM TO BE SOLVED: To provide a means by which gas samples can be sampled easily with a simple constitution. SOLUTION: In the gas-sample sampling apparatus 1, an orifice-type vacuum pump 13 is installed in a pipeline 12 which connects a sampling chamber 10 used to sample the gas sample to an analyzer 11 used to analyze the gas sample. A gas to be sample which is sucked by the vacuum pump 13 is sent to the analyzer 11 as atmospheric pressure, and the gas sample is analyzed. The gas- sample sampling apparatus in which it is not required to install many valves, an inert-gas injection means or the like, whose constitution is simple and which is low-cost can be provided, and its operation is easy.
