Abstract
The present invention provides a thermal conductivity detector capable of realizing high detection performance even with the use of a miniaturized heating element, and expanding an effective applicable temperature range of a heating element, and to provide a gas chromatograph using the same. The thermal conductivity detector comprises a flow-path through which a measurement gas is caused to flow, a heating element disposed inside the flow-path, the heating element being formed on the substrate, for detecting thermal conductivity of the measurement gas according to magnitude of an amount of heat taken away from the heating element by the measurement gas, wherein said heating element is provided with a beam including a part where the beam is folded at a predetermined angle, the part being formed at the central part of the beam.
