PROBLEM TO BE SOLVED: To send high-concentration sample gas, in a short time, by adsorbing the sample gas uniformly, and by preventing re-adsorption of desorbed sample gas. SOLUTION: In this sample gas collection device 1, having a hollow member 11 having an introduction port 11a for introducing the sample gas and an exhaust port 15a for exhausting the introduced sample gas; a collection agent 12, stored in the hollow member 11 for collecting the sample gas; and a heating means 13 for desorbing the sample gas collected by the collection agent 12 by heating the hollow member 11, for collecting the sample gas introduced into the hollow member 11 by the collection agent 12 in a low-temperature state, and desorbing the sample gas collected by the collection agent 12 in a high-temperature state, the collection agent 12 is formed in a shape where the distance from a place where the sample gas introduced from the introduction port 11a is collected uniformly and the collected sample gas is desorbed to the exhaust port 15a is substantially uniform, and the hollow member 11 is formed in a shape storing the collection agent 12.
