A voltage detecting circuit for detecting a state of a first voltage includes a detection voltage generating circuit for generating a detection voltage depending on the first voltage, a reference voltage generating circuit for generating a reference voltage, a comparison circuit for comparing the detection voltage with the reference voltage and outputting a result of the comparison as a detection signal, and a control circuit for controlling at least one of the detection voltage generating circuit, the reference voltage generating circuit, and the comparison circuit so that at least one of these circuits operates intermittently.
