Ceramic heater module control apparatus, and ceramic heater unit

A ceramic heater module control apparatus for controlling a ceramic heater module which includes a ceramic heater having a ceramic base body including a resistive heating element embedded therein, and a case housing the ceramic heater and having an inlet and an outlet through which a liquid medium flows, wherein

• the ceramic heater module control apparatus is configured to
• obtain, as an outlet temperature, a temperature on an outlet side with respect to the ceramic heater module;
• determine whether or not a predetermined stop condition is satisfied, on the basis of a temperature difference between a start temperature and a detection temperature, the start temperature being the outlet temperature at an energization start time point at which energization of the resistive heating element with a predetermined power is started, and the detection temperature being the outlet temperature obtained at one or a plurality of specific time points after the energization start time point;
• and
• stop the energization of the resistive heating element in the case where it is determined that the stop condition is satisfied.
