PROBLEM TO BE SOLVED: To provide a thermal conductivity detector in which a TCD cell has a good temperature stability and is stabilized in a short time. SOLUTION: In setting the TCD cell 13 via an insulating thin material 28 onto a temperature control block 26 and moreover heating the cell by a heater controller 24, a temperature of the TCD cell is made higher than a final reach temperature through the temperature control for a fixed time by a temperature higher than a set temperature, and then the temperature is controlled by the original set temperature. The TCD cell is thus brought closer to the set temperature from the side of higher temperatures than the final set temperature.
