In a constant voltage generating circuit and a reference voltage generating circuit, a band-gap circuit operates by using, not a power source voltage, but a constant voltage generated in a constant voltage circuit as a power supply voltage. The constant voltage circuit is equipped with a constant voltage circuit having transistors connected in series and a capacitor, and a transistor is equipped between a constant current circuit and the constant voltage circuit. Furthermore, transistors are added to prevent an early effect of the transistors in the constant current circuit.
