Abnormality detecting apparatus

摘要

An abnormality detecting apparatus (1) includes a power supply portion (10) applying a voltage to electrodes (100a) provided at both surfaces of a light control glass (100) adapted to be provided at a vehicle to change a transparency of the light control glass (100), a detection portion (11) detecting a detectable amount obtained on the basis of the voltage applied to the electrodes (100a), and an abnormality determination portion (12) determining whether or not an abnormality occurs to the light control glass (100) based on a predetermined detectable amount and the detectable amount detected by the detection portion (11).
