ータ断線検出回路。[Claims for Utility Model Registration] Detection means for detecting a heater current and outputting a detection output at a detection level corresponding to the heater current value based on this detection; a setting means for outputting a set output of a set level determined corresponding to a detection level of the detection output, and a comparison between the detection level of the detection output given by the detection means and the set level of the set output given by the setting means. In the heater burnout detection circuit for a temperature controller, the setting means is configured to hold the detection output given from the detection means to a peak value, and the peak value holding means holds the detection output given from the detection means to a peak value. A heater breakage detection circuit for a temperature regulator, comprising: attenuator means for attenuating a hold output given by the hold means to 1/N and outputting the resultant to the comparison circuit as the set output.
