PROBLEM TO BE SOLVED: To faithfully detect the sample gas component, which is adsorbed and collected by an adsorbing material, by a smell sensor. SOLUTION: This smell discrimination system is equipped with a gas sensor 17, a collection pipe 15 filled with an adsorbing material for adsorbing a smell component in a sample gas, a sample gas supply part 11 for supplying the sample gas to the collection pipe 15, a heating part 14 for heating the collection pipe 15 in order to desorb the smell component adsorbed by the adsorbing material and a carrier gas supply part 16 for supplying a carrier gas to the collection pipe 15 in order to discharge the smell component desorbed from the adsorbing material and further equipped with a gas concentration preparing part 13 for once holding the sample gas and the carrier gas in a space and discharging them after the concentration of the smell component is uniformized.
