PROBLEM TO BE SOLVED: To provide a voltage error amplification circuit enabling cost reduction and obtaining a high DC gain, and a stabilized power supply causing small variance in output voltage Vout. SOLUTION: In a voltage error amplification circuit equipped with a shunt regulator having a common potential terminal connected to a common potential point and a reference potential terminal connected to an output voltage, a constant voltage means is disposed between the common potential point and the common potential terminal.
