PROBLEM TO BE SOLVED: To provide a band gap reference circuit having satisfactory temperature characteristics and a semiconductor device having the band gap reference circuit. SOLUTION: The band gap reference circuit is so configured that a fixed band gap voltage is generated by connecting a resistance between emitters of a pair of transistors which have bases connected in common and are different by current densities, and adjusting base potentials so as to equalize collector currents of both transistors. The band gap reference circuit has a current adjustment means which adds currents to which an integral multiple of the collector current is distributed at an adjustable ratio, to emitter current of respective transistors.
