An imaging device is disclosed. The device includes: a unit pixel that outputs an analog electric signal in accordance with a signal charge; a local voltage supply circuit that generates a local voltage different from an operation voltage; a reference signal generation section that generates a reference signal based on the local voltage provided by the local voltage supply circuit; and a processing section that converts, by referring to the reference signal generated by the reference signal generation section, the analog signal provided by the unit pixel into a digital signal. In the imaging device, the reference signal generation section keeps constant a load current of the local voltage supply circuit in an operating state.
