Provided is a reference voltage circuit for generating a low constant voltage (1.25 V or lower) having less temperature dependence. The reference voltage circuit includes: a bandgap voltage generation circuit including two PN junctions, for outputting a voltage (Vk) which is based on any one of the two PN junctions and a current (Ik) which is based on a voltage difference between the two PN junctions; and a voltage divider circuit for dividing the voltage (Vk). The voltage divider circuit corrects a divided voltage based on the current (Ik) input thereto, and outputs the corrected divided voltage as a reference voltage.
