Disclosed is a reference voltage generating circuit including first to third current-to-voltage converter circuits, a control circuit for exercising control so that the terminal voltage of the first current-to-voltage converter circuit is made equal to that of the second current-to-voltage converter circuit, and current mirror circuits for driving the first to third current-to-voltage converter circuits. A preset voltage of the third current-to-voltage converter circuit is used as a reference voltage. The first current-to-voltage converter circuit is composed of a diode. The second current-to-voltage converter circuit includes a plurality of parallel connected diodes, a resistor connected in parallel with the plural parallel connected diodes and a resistor connected in series with the parallel-connected diodes and the resistor. The third current-to-voltage converter circuit is composed of a resistor.
