Summary:PROBLEM TO BE SOLVED: To provide a compact gas component detection device having a simple structure for accurately measuring the concentration of a gas component as a measurement object, even when sample gas contains a plurality of gas components. SOLUTION: The gas component detection device includes: a gas introduction section for introducing the sample gas; a gas separation section connected to the gas inlet section; a flow path switching section connected to the gas separating section and having a plurality of connection flow paths for switching a flow path connected to the gas separating section to any one of the plurality of connection flow paths; and a gas detecting section, provided in at least one of the plurality of connection flow paths. The gas separation section is preferably formed of a chromatography column having therein a flow path having a width and a depth of micro order. COPYRIGHT: (C)2011,JPO&INPIT
