Abstract: A thermal conductivity detector that causes a fluid to come into contact with the surface of a heated temperature sensing element, that causes the temperature of the temperature sensing element to change according to the thermal conductivity of the fluid, and that detects the fluid based on a change in the electrical resistance of the temperature sensing element at that time or on a change in the value of a current to be applied to the temperature sensing element is provided. The thermal conductivity detector includes a cell space where the temperature sensing element is accommodated and to which a fluid is introduced and from which the fluid is discharged, a buffer space that is connected to a fluid outlet of the cell space, and a discharge channel that is connected to a fluid outlet of the buffer space.
