A reset circuit includes a first voltage generation unit that generates a first voltage based on a first power supply voltage output from a first constant voltage source, and a comparator that includes a positive power supply terminal to which the first voltage is input, a negative power supply terminal connected to a ground circuit, one input terminal as one of positive and negative input terminals and to which a reference voltage is input, another input terminal as the other of the positive and negative input terminals and to which a divided voltage obtained by dividing a second power supply voltage supplied from a second constant voltage source different from the first constant voltage source and to be detected based on the reference voltage is input, and an output terminal that outputs a reset signal to reset a subsequent circuit to the initial state according to a comparison result.
