An energization control apparatus (30) includes an FET (32), a thermistor (34) and anomaly detection means (36). The anomaly detection means (36) includes temperature-difference calculation means (45) and sensitivity anomaly determination means (41). The temperature-difference calculation means (45) acquires a first temperature measured by the thermistor (34) before startup of a vehicle or within a fixed period after the startup, acquires a second temperature measured by the thermistor (34) at the time when a predetermined wait time has elapsed from the time of acquisition of the first temperature, and calculates the difference therebetween. The sensitivity anomaly determination means (41) determines, from the difference, an anomaly of the thermistor (34) associated with its sensitivity to a temperature to be measured.
