摘要： PROBLEM TO BE SOLVED: To provide a heater energization control apparatus capable of performing correction with high accuracy to a difference in individual properties of heating resistors of a heater in which energization is controlled by a resistance value control method. SOLUTION: A pre-correction resistance value necessary for calculating a target resistance value of a heating resistor applied as a control target when performing the PI control of heat-retention energization (S73) to the heating resistor in which a resistance value is changed according to a temperature change with a positive correlation is acquired when an engine is stopped (S41:NO). Thus, the acquired corrected resistance value is not affected by disturbance which is generated accompanied by the drive of the engine, and the temperature of the heating resistor can be kept at a target temperature with high accuracy by controlling the energization to the heating resistor by using the target resistance value calculated (S71) on the basis of the corrected resistance value and water temperature information.
