The present invention provides a reference voltage generating circuit capable of improving a temperature dependence characteristic by a simple configuration. The reference voltage generating circuit includes: a reference voltage generating circuit element including a first diode characteristic element and a second diode characteristic element, a density of a current flowing through the second diode characteristic element being different from a density of a current flowing through the first diode characteristic element, the reference voltage generating circuit element being configured to output a reference voltage generated based on a difference between voltages respectively applied to the first diode characteristic element and the second diode characteristic element; a first adjusting circuit element configured to adjust a first-order temperature coefficient of the reference voltage; and a second adjusting circuit element configured to adjust a second-order temperature coefficient of the reference voltage. |
