PROBLEM TO BE SOLVED: To provide a TCD which is especially effective for a single flow cell, capable of correcting temperature drift or the like. SOLUTION: In this TCD, constituted so that a filament (temperature-sensing element) R1 forms at least one side of a resistance bridge circuit 1 fed from a constant-current source 2, a correction circuit 4 for correcting an output signals S, based on the change of a voltage Vo fed from the constant-current source 2 to the resistance bridge circuit 1. Hereby, the temperature drift can be compensated, even in the case of a single-flow cell TCD having no correction means hitherto, and the stable TCD which is applicable even for high sensitivity analysis is provided.
